Tulisa performed Live from the 34th Floor of the BT Tower last night (10.12.12).

The 'Young' singer gave a special stripped back concert at the London landmark for the BT Infinity Presents series of concerts, showcasing songs from her debut solo album, 'The Female Boss', which was released last week.

The 24-year-old star sung singles 'Sight of You' and 'Live it Up' for both the audience at the tower and thousands of fans who were watching live at home on YouTube.

New track 'Visa' received a rapturous reception, and although fans had voted for her to cover David Guetta and Sia's huge single 'Titanium', she instead opted to sing a Cyndi Lauper's 'Time After Time', saying: ''I am, after all, The Female Boss.''

Tulisa finished her set with number one single 'Young' before telling the audience: ''Merry Christmas Everybody... Now, where's the fish and chips,'' referring to the event's catering.

Tulisa seemed more at home in the intimate environment compared to her performance in front of millions when she appeared on 'The X Factor' - on which she also appears as a judge - in the UK, two weeks ago.

Talking about her appearance she told TV show 'This Morning': ''That was terrifying, I don't even want to talk about that. I have never been so scared in all my life. For some reason, just doing it there, the pressure is completely different. I don't even get nervous anymore usually and I literally was just shaking. My legs started going, I thought I was going to faint. I couldn't control what I was doing.''

The series will continue when Rizzle Kicks perform at theBT Tower on January 15. For more information visit www.youtube.com/btinfinitypresents
