Tulisa Contostavlos is finding it tough to ''know who to trust'' since her sex tape was released.
The 'X Factor' judge - who used to date her N-Dubz bandmate Fazer - was left devastated after X-rated footage of her and ex-boyfriend Justin Edwards was released online in March, and the 23-year-old singer admits the scandal has made her re-think her relationships.
Tulisa - who is dating former 'Skins' actor Jack O'Connell - said: ''Some people base their careers on having a celeb relationship, but that's not what I'm about.
''It's hard to know who to trust. That's usually why celebs end up with other celebs.''
The 'Young' hitmaker - who topped the FHM 100 Sexiest Women in the World list earlier this week - is enjoying being able to choose how she wants to dress after being forced to style herself like a boy to fit in with her N-Dubz bandmates Dappy and Fazer's urban look.
She added to We Love Pop magazine: ''It wasn't always exactly how I wanted to dress. It was about me fitting into a band. You kind of accommodate for the people you're with.''
''If you're in a boy band you're not going to have one guy in an Armani suit and the other in an Adidas tracksuit, are you?
''But now I'm on my own, doing my own thing, I get to embrace what I actually like. I don't have to worry about what the boys wear.''
