The former X Factor judge arrived at DSTRKT night club in the capital on Tuesday night (6 August) wearing a black leather skater skirt and tiny black crop top teamed with a cropped tuxedo jacket and black heels.
She kept her accessories to a minimum, wearing just a statement gold necklace.
Before leaving for the club, Tulisa had shared a photo of her outfit with fans via Instagram, adding: "Swagged out n ready 4 my baby gal @chelseehealey bday, panic stations over thanks to @Official_Kaos for sortin out my hair lastmin.com! Love ya guys xx."
It seems Tulisa had earlier spent her day working as she uploaded another two pictures of herself taken for an upcoming campaign.
The 'Young' singer wrote: "Final shots for hair colour n makeup shoot! Love my hair n makeup by @catherineboden extension by @russianlengths and captured by @ladydphotography they r all damn good at what they do check em out."
Tulisa's kept a relatively low profile lately following her arrest and bail on suspicion of supplying drugs back in June. She is scheduled to appear in court to answer bail in October.
Tulisa hasn't yet addressed the allegation but a friend arrested alongside her has insisted they are innocent.
Career-wise, the former X Factor judge has just announced she's penned her first novel called Sky which is about a young girl's rise to fame.
