Christmas is fast approaching, but you would think it was the height of summer judging from Pixie Lott's ensemble last night.

The 20-year-old squeezed into the tiniest of skirts and a barely-there vest top for a night on the town with her boyfriend Oliver Cheshire.

The pair headed to London's Boujis nightclub after Pixie performed for the Capital FM Jingle Ball concert at the O2.

Oliver, who has been dating Pixie for over a year, looked sharp in a black suit and white shirt.

Pixie showed off her endless legs with a waisted black miniskirt, looking toned in a pair of heeled ankle boots.

Her upper half must have been a little chilly, as the star wore only a cream vest top embellished with black lace.

They certainly made a good-looking pair- and no wonder since the pop star's beau is a successful model.

The 22-year-old, who is represented by Select Model Management, has been the face and body for Calvin Klein Jeans and D&G, in addition to the Paul Smith Spring 2011 Swim Campaign.

Only hours before her rendezvous with Oliver, Pixie wore an equally sexy outfit as she sang alongside stars such as The Wanted at the Capital FM Jingle Balls Christmas concert at the O2.

Saucy: Pixie's dress featured a cutaway section on her chest

Pixie donned a very fitted short black dress, featuring a cutaway section at the chest to show off yet more of her enviable figure.

Excited for the show, the singer had tweeted beforehand: 'Just did Royal Variety rehearsals in Manchester now back to London for Jingle Bell Ball @capitalofficial yeyeyyeyeeye'

Pixie revealed a rather less starry side when she popped into a Manchester newsagents the day before to pick up a lottery ticket.

Killing some time in between her Manchester and Liverpool shows, the star chatted on her mobile as she picked up her numbers in the local shop.

She was shopping with friends in Manchester city centre after kicking off Christmas at the MEN arena alongside JLS, Matt Cardle, and Olly Murs.
