N-Dubz rapper Fazer was at Tulisa Contostavlos' side when X-rated footage of her was leaked online last month.

The 25-year-old star - who split up with the 'X Factor' judge in January after 18 months of dating - comforted the brunette singer when the sex tape with her ex-boyfriend Justin Edwards, aka MC Ultra, was first broadcast on the internet, and he insists she will be "absolutely fine" despite initially being "upset".

He said: "I was with Tulisa when it happened. She was upset but she's a strong lady she'll be absolutely fine, man. Don't worry about that."

Fazer and Tulisa - who have known each other since they were 11 after forming N-Dubz with her cousin Dappy Contostavlos - are still "mates" and often chat, despite romantically going their separate ways earlier this year.

Fazer - whose real name is Richard Rawson - exclusively told BANG Showbiz: "She's cool and we are all still mates. We still talk to each other every now and again."

Despite Tulisa confirming last month that the musical trio have "split", Fazer is fully expecting the 'Bad Behaviour' hitmakers to return to the music scene to record a fourth studio album next year.
