A/N: This is my birthday fic, and the reason I'm posting it a day early, is because it's my friend Jess' Birthday today, and seeing as I forgot to get her a card (sorry Jess, but be happy with the Rooney CD, Ok?) I'm splitting this story in half – thus making it a two-parter – and posting the first bit on her birthday, and the last bit on mine. Therefore, it makes everyone happy, and it'll keep you lot hanging (I hope). Well, read and review, the next part will be up tomorrow!

:-)

Disclaimer: I don't own it, never will so call the damn lawyers off!

It was his birthday. Yes, Michael Moscovitz was turning the grand old age of eighteen. You know, if he lived in England, he would be able to buy a drink … legally. Not that he'd want to of course …

And what a birthday it was. Good and bad. So far, he'd managed to get a new cell phone, a new laptop case and a load of albums, including Rooney, Phantom Planet, and this UK band called The Darkness. All in all, it was turning out to be a pretty good birthday. Except for the fact his little Princess wasn't with him.

Yes, Mia Thermopolis, or Amelia Renaldo in some circles, was his girlfriend now. It came as a surprize to both him, and her when they found out everyone else had known for some time. A couple of people had even put a bet on to see how long it would take them to realize it.

 None of them guessed 7 years though.

When the happy couple finally got together, there was much laughter from everyone, although Michael and Mia didn't see what was so funny. Here they were, just finding out that all the misery of thinking their love was unrequited, could have been avoided if only one of their so-called friends had opened their mouths and told them!

But they soon saw the funny side and joined in laughing. Eventually.

This all added up to why Michael's birthday was great … and not so great. You see, Mia hadn't mentioned anything about his birthday when she called him the previous night. In fact, she'd avoided it for as long as humanely possible. When he brought it up, she'd muttered something about parliament being in session, and hung up. What a strange birthday this was turning out to be.

Why was Mia avoiding the subject of his birthday? He hadn't done anything wrong had he? Maybe he had. Maybe, when he'd called her the night before, he'd unwittingly said something that was offensive to her, or Genovia. No, he couldn't have done. Unless the weather and what was on TV last night is offensive.

Maybe it was. You never could tell with those Genovians. You only had to look at Grandmere to prove that.

So whom else should he ask, but his lovely girlfriend's best friend, Lilly Moscovitz. Who also happened to be his sister – Unfortunately.

"Lilly …?" he questioned, knocking once before barging into her room.

"Oops, gotta go. Bye" she hung up quickly, her face rapidly turning red. 'Kind of like Mia' Michael thought, before narrowing his eyes and taking a seat, uninvited, on Lilly's bed.

"Who was that?" he asked suspiciously.

"Why are you in my bedroom? Are you spying on me?" she accused, setting the phone back down onto the table and moving directly in front of her brother.

"Because I am, No I'm not, and you haven't answered the question." He rattled off, still looking at the phone.

"What question?" she asked him, taking a step to the side and blocking the phone from his view.

"Who was on the phone?" he asked again, looking up at her and raising one eyebrow.

"Oh. That. Well … um, it was just a … a …double glazing salesman! Yup, that's all. Now get out." She said, walking to the door and opening it.

"You're lying." He stated calmly, not budging from his spot on the bed.

"No I'm not."

"Yes you are."

"No I'm not."

"Yes you are."

"No. I'm. Not."

"Yes. You. Are."

"How do you know?" Lilly finally asked after deciding to be the bigger person and end the endless bickering.

"Well, your eye is twitching, you can't stop moving your left foot and your hands have turned white because you're squeezing them so hard." He replied coolly.

"Oh. That doesn't necessarily mean I'm lying." She stated, taking a seat on the floor and trying to control her hands.

"Yes it does."

"No it doesn't."

 "Yes it does."

"No it doesn't."

"Yes. It. Does."

"No. It Doesn't."

"STOP!" She yelled, beginning to see a pattern emerging. "Look," she continued "Ok, maybe I'm angry at the fact my brother barged into my room, interrupted a personal phone call and is now starting stupid little fights which have no significance or meaning at all."

"So it was a personal call then." Michael said, leaning back on the bed and smirking at her.

"No - Oh bugger." Lilly realized too late, what she had said.

"So … now we've got that little misunderstanding cleared up, are you going to tell me who was on the phone?" He asked her, trying his hardest not to add a smart-ass comment on the end but still sounding very patronising.

"No. Get out!" She yelled, grabbing him by the arm and attempting to pull him out of the room.

"Not until you tell me who was on the phone." He said, putting all his weight onto his legs and making it even more difficult for Lilly to pull him out.

"Fine. It was mom. Ok? Now go away." She muttered, letting go of his arm.

She sounded convincing so he let it go and ambled slowly out of her room, shouting a "thanks" over his shoulder. What he didn't see, was Lilly's evil little grin, and the crossed fingers hidden behind her back. She may have sounded convincing but she was as much of a liar, as his dear Mia was. Speaking of Mia, she figured she'd better call her back.

"Hello?" Mia answered the phone 5 minutes later after sneaking past her dad's office and into the bathroom. Grandmere wouldn't like it if she knew the Princess was calling America at 3am.

"Hey Mia, Michael's gone." Lilly muttered, shutting her bedroom door.

"Good … let's get down to business …"

Happy Birthday Jess!!
