Chapter One – Fifteen Years ...

It was hard to believe that Hannah Montana had been around for 15 years. Not only had she been around but she had also been top of the charts with every one of her eight albums. Now twenty eight, Miley Stewart aka Hannah Montana was probably one of the happiest women alive and she knew just how lucky she was. She had married her high school sweetheart right out of high school and had one daughter who was four years old next week. Nobody would have guessed, least of all Miley herself, that she would fall in love with her best friend, with her female best friend that is. But fall in love with Lilly, Miley had and she hadn't looked back. She sighed happily as she looked into the mirror of the dressing room. She loved putting the Hannah wig on and everything that came with it and she also loved being able to take the wig off and go home as herself. She finished brushing the wig just as the door opened behind her and the two most important women in her life entered.

"Momma!" little Sydney exclaimed excitedly as she ran into Miley's arms. She laughed and hugged her daughter to her and watched as Lilly, her wife aka Lola Montana, closed the door behind them.

"And how's my little bud doing today?" Miley asked happily.

"I'm good Momma, Mommy and me painted this morning, see I did you a picture of us" she told her Momma proudly and pushed a folded piece of paper in her hand. Miley smiled and opened it. There was her and Lilly, the bigger stick figures each the same except for having brown or yellow hair and then a smaller one also with brown hair. By this time Lilly had made her way over to the chair and leaned forward to place a soft kiss on the lips of her wife.

"Hi hun" she smiled up at Lilly.

"I missed you so much sugar," Lilly whispered into her ear, she knew Miley loved it when she called her sugar, "Tonight Syd is staying with Grandpa Robbie" she continued before she pulled away and smirking at her wife. Sydney decided enough was enough and she wanted the attention back.

"Momma! My picture, what do you think of it, I spent a whole hour on it" she smiled proudly. Miley blinked, her mind still full of the night she was going to have but she quickly cleared these thoughts, glared at her wife playfully and then smiled at their daughter.

"It's fantastic bud" she agreed, "Can I keep this in here?" she asked. Sydney nodded her head enthusiastically and smiled as she pulled on her wig. "What's up bud?" she asked.

"This new wig is itchy" she complained.

"Well that's Mommy's fault" Miley smirked at her wife. Lilly had been fine taking Hannah's surname for Lola's but she had insisted that Savannah Montana's hair colour change as often as Lola's did.

"But she looks so cute" Lilly defended. Today both Lola and Savannah were wearing their cherry red wigs. Further discussion was halted by a knock at the door which Lilly quickly walked over to and opened. There stood Robbie Ray Stewart in his usual disguise of a suit, a moustache and a hat.

"Grandpa!" Sydney squealed as she jumped from Miley's knee and into the waiting arms of her Grandfather.

"Hey there little mighty mouse" he joked with her, "You ready for a fun filled night at your Grandpa's house?" he asked.

"Daddy, what did we say last time?" Miley asked firmly. Last week, Robbie Ray had let his granddaughter wrap him around her little finger and they had ended up staying up all night watching Disney movies. The next day, Sydney had missed her swimming lesson because she was too tired to go.

"It's ok Bud, that won't happen again" he promised.

"Do you promise Sydney Stewart?" Lilly asked her daughter sternly. Sydney looked up at her mommy and gave her an innocent smile that she was so used to seeing from Miley.

"I promise mommy" she said solemnly.

After another few minutes of goodbye, Miley was rushed to the stage entrance with Lilly as Robbie Ray took his granddaughter home. She quickly went through her warm up exercises before she turned to Lilly who smiled at her.

"Knock 'em dead Hannah" she told her as she placed her arms around Miley's waist.

"I will Lola, how can I not when it's for you, it's always for you" Miley smiled softly. Lilly didn't respond verbally, she leaned forward and passionately kissed her best friend instead, allowing all the emotion she was feeling at hearing that to be felt through the kiss. "I love you" Miley whispered as they parted.

"I love you too" Lilly smiled, "Now go, don't keep your fans waiting" she chastised before letting her go and gently tapping her on the bum towards the stage. Miley's laughter stayed with Lilly for the whole of the concert.

During the concert, Lilly began to think back over the last 15 years or so. The day that she and Miley had got together had been as much of a surprise to them as it had been to everyone else, but they truly loved each other and had dealt with every single problem together. It had been like that when they were just friends as well, on reflection maybe they should have realised just how perfect they were for each other sooner. They hadn't but everything turned out perfectly as it was and she wouldn't trade any of those years for anything. The hardest part, most people might think, would be telling their families and being accepted but actually, the hardest bit was when they decided that they both wanted kids. It was at that time that Lilly hated for the first time that they were both women. She wanted to bear Miley's child and Miley wanted to bear her child and at first they had no idea whether it would even be possible. They had discussed all options, after the initial tears that came with this realisation, sperm donors, adoption, the usual stuff but then a break through treatment became available called Stem Cell Reverse Engineering. Lilly still didn't know exactly how it worked. All she knew was that they had taken some of her epithelial cells and somehow turned it into spermatozoa and that it gave her and Miley the most perfect little girl. They hadn't even cared whether they had a girl or a boy. They had recently been back at the doctor's, this time to try and make Lilly pregnant with Miley's child. They were due back at the doctors' office this week to find out if they had been successful, Lilly hadn't taken a home test at all, just as they hadn't when Miley was pregnant with Sydney, they wanted to wait for official confirmation from the doctor. Lilly had tried to figure out if she felt pregnant or any different at all but she didn't. She placed her hand over her stomach; she could be pregnant right now. She could be carrying Miley's child, she smiled softly at the thought. She was pulled from her musings by the thunderous applause and Miley speaking to the crowd.

"Thank you Malibu! You've been great!" She thanked, before moving off stage and into Lilly's arms. "Let's go home" she whispered into her ear. Lilly just smiled, nodded and took her arm as they both walked towards the exit and their ride home.

Later that night as both Miley and Lilly fell exhausted against each other into the bed they had shared as lovers for almost 11 years, Miley's heart was filled with happiness as she thought about all the blessings she had in her life. She felt Lilly's breathing even out indicating she had fallen asleep and Miley moved her hand to rest on Lilly's stomach, she was really excited that they could soon be parents again. With this happy thought, Miley followed Lilly to sleep.

Nothing could possibly destroy their happiness ... could it?
