Taking to the stage at Soho's Freedom Bar, Pixie made sure all eyes were on her as she paraded her pins in this velvety number.
Channeling her inner minx, Pixie wore just a baby pink leotard for her performance.
And featuring a strategically placed blue and yellow fluffy heart down below, we're not quite sure what her mama would do if she saw Pixie in her saucy stage getup...
She definitely turned heads that's for sure!
Going all out for her secret pop up gig, the excited 'Lay Me Down' singer even sported her brand new shoes for the occasion. Earlier this week Pixie posted a picture of her new Stella McCartney kicks to Instagram.
Choosing to wear her star-design platforms for their first outing last night, we can't help but think the singer's fancy footwear was a little overshadowed...
Teaming her new shoes with fishnets and a pink babydoll robe, Pixie finished off her look with lashings of mascara and lots of lift in her blonde locks.
Taking to Twitter, Pixie unveiled her stage appearance to her fans. On her way to the London venue, she tweeted: "Doing a secret pop up gig tonight @FreedomBarSoho get there now! Am on at 12.15pm wowowop. En route, see you cats there."
The blonde beauty arrived at the bar on her own and without boyfriend Oliver Cheshire who she has rarely been seen without lately.
Just the night before (29 July), Pixie and Oliver were spotted in the capital enjoying a romantic dinner together. And despite Pixie still baring her legs in a chic double-slit dress, the star was a little more covered up for date night.
