Attending Chopard's Christmas party with boyfriend Oliver Cheshire in tow, Pixie oozed Hollywood glamour in her vintage ensemble.
Last month, Pixie and Oliver attended their first Christmas party of the year, and continuing their festive fun yesterday evening, the couple rocked up to yet another showbiz bash.
Never failing to impress in the style stakes, Pixie and her model beau looked effortlessly chic for their night on the town.
While Oliver looked dapper in a three piece suit and tie, Pixie smouldered in a gorgeous 1960s mini dress, with sequin and tassle detailing.
Teaming her frock with a pair of silver peep-toe heels, the 'Lay Me Down' singer amped up the glam with her blonde locks slicked back into a side parting and bold red lipstick on her lips.
At the party, the pair were joined by a whole host of celebs including Mean Girls star Lindsay Lohan, Jourdan Dunn and Millie Mackintosh - who attended the do after watching the Victoria's Secret Fashion Show earlier on with BFF Rosie Fortescue.
Pixie's Christmas night out with her other half comes as a relaxing break from her busy schedule lately.
As well as promoting new music material - Pixie has just released her greatest hits album Platinum Pixie - the 23-year-old has been practicing her footwork ahead of Strictly's next live show this Saturday.
With the final just weeks away, the competition is stepping up a gear and, no doubt, Pixie will be training hard in her bid to win the coveted Mirrorball trophy.
Last week, Sunetra Sarker was the ninth celebrity to be voted out of Strictly Come Dancing.
Joined by Mark Wright and his partner Karen Haeur in the bottom two, Sunetra was sent home after a unanimous vote by the judging panel.
Following her exit, she said: "It's been such a once in a lifetime opportunity to be able to do this.
"I'd like to thank Brendan for being just so committed and understanding, and such a natural dancer - you've been great - thank you so much for everything."
Strictly Come Dancing continues this Saturday 6 December at 7pm on BBC One.
