The 'Young' singer looked lovely in a vibrant yellow dress and black heels as she made her way out of the London studios on Tuesday. (Shame about the unglamorous bin bags in the background!)
We couldn't get a good look at her hairdo but it seems that she's wearing a low ponytail – and from what we can see, it looks gorgeous!
Tulisa was back at work today after finding herself unexpectedly drafted back on to X Factor at the weekend as a replacement for poorly Mel B.
It was revealed on Saturday that Mel was too ill to join the judges on the live show - part one of the grand finale – so Simon Cowell called on former judge Tulisa instead.
Tulisa joined Simon, Louis Walsh and Cheryl Fernandez-Versini for Saturday's show from Wembley, where she supported Mel's finalist Andrea Faustini in Mel's absence.
Mel returned the next night.
Tweeting at the weekend, Tulisa said: "I had a brilliant time on the show last night and I'm so pleased @OfficialMelB is well and back for the final show! Have a good one babe ."
Tulisa has spoken lately of how she'd happily return to X Factor if she had the chance, saying she's in a good place in her life right now to be undertaking the opportunity.
She appeared on the show twice this year before replacing Mel B: once at judges' houses with Louis Walsh in Bermuda, and again at a recording studio session.
Tulisa left X Factor in 2013 to focus on other projects. She's still the only judge who has managed to mentor a group to success, winning in her first year with Little Mix.
