X Factor judge Tulisa Contostavlos cut short her first public outing since her sex tape emerged online after she became paranoid that people were judging her at a backstage party following a concert by Drake.
According to The Sun, the 23-year-old was embarrassed when she bumped into boy band JLS in her private box at the start of the concert.
Tulisa apparently became red-faced after she realised that they must have watched the raunchy video showing her performing a sex act on her former boyfriend, rapper Justin Edwards.
A source close to the former N-Dubz star told the paper: "She knew the JLS boys were going to be there, but felt really awkward when she walked in because she presumed the lads had seen the tape.
"She said a quiet 'Hello' to them - but then went straight out the back door, let out a big squeal and took a deep breath before going back in to face them."
Another source said: "Tulisa and her pals hardly spoke to JLS throughout the gig. It was a really uncomfortable atmosphere because she is so embarrassed about the tape."
Even though Drake showered the "Female Boss" with affection and even called her "Princess of the UK", she soon made a swift exit.
Edwards, aka MC Ultra, appeared in court to defend himself over claims that he leaked the seven-minute tape featuring Tulisa.
He maintained that he was not responsible for leaking the video and also claimed in a written statement that she had "persuaded" him to film the intimate moment.
His statement said: "I am disgusted it has been [leaked] and regret ever allowing the claimant to persuade me that we should film ourselves.
"I simply do not, and never have, possessed the film referred to."
The singer is currently seeking damages of up to £100,000 from him over humiliation caused by the leak.
