A worse for wear Amelia Lily marks milestone by partying til the early hours in VERY short dress

 She was only 16 when she first auditioned for The X Factor.
But now Amelia Lily has come of age as on Tuesday she turned 18.
And in true pop star style the singer ensured she celebrated the occasion by making the most of her new found 'legal' age and headed out to party at London drinking hot spot Mahiki.

 The singer ensured all eyes were on her as she dolled up for the evening in a minuscule figure hugging dress with sheer detailing.
Amelia showed off her legs as her pals and boyfriend Ollie Mack joined her by her side to mark the occasion.
Lily looked confident as she happily posed for photographs in the skimpy ensemble, while she wore her pink dip dyed locks down and curly.

 She finished her look off with peep toe heels for the grown up look with dark red nail polish.
Amelia even had the likes of The Wanted's Tom Parker and Jay McGuiness turn up to the club to toast her birthday, too.
And they'd all clearly had a good night as Parker walked out of the venue with a large grin on his face flanked by his girlfriend Kelsey, who draped herself over him.

 Birthday girl Amelia also seemed in a merry mood as she held hands with a girl friend and her electrician boyfriend upon leaving the venue.
Although she probably flashed a bit more than she intended to as she climbed into the back of her waiting car to finally call it a night at 3.30am.
The star flashed her under garments as she adjusted herself in the seat.

 Obviously keen to officially become an adult, the singer wrote on her Twitter page ahead of the party on Monday: 'So excited for tomorrow! Finally my 18th woooooo.'
And in particular she was overjoyed to be legally able to drink in the UK.
She added: 'Buzzinggggg! #legal,' next to a picture of a bar stocked with alcohol.
The star certainly wasn't short of presents to mark the occasion either.

 Not only was she presented with a brand new car, but her management gave her a white Michael Kors watch.
And she'd managed to bag Henry Holland as the DJ for the night at her party.
She added on Twitter: 'Once again everyone thank you so much for my birthday messages! Much love!'
