Tulisa Contostavlos' bodyguard sits in on her first dates.

The 'X Factor' judge employs best friend and personal assistant Gareth Varey to vet potential lovers to make sure she doesn't run into any romantic difficulties following her recent allegation that ex-boyfriend Justin Edwards, aka MC Ultra, leaked an explicit video of her onto the internet.

She said: "Gareth doesn't leave my side, he even supervises dates. If I started seeing a guy Gareth would be on the first four dates, we come as a package.

"He doesn't necessarily always get involved, he's just always there."

The 23-year-old singer has accused Justin of "violating" her and trying to "ruin" her career, and she has insisted she will never fall victim to a similar incident in the future.

She added to BBC Radio 1 DJ Chris Moyles: "I know for a fact this will never happen again."

The brunette beauty is now dating former 'Skins' actor Jack O'Connell and the pair have vowed never to discuss their relationship, while the N-Dubz singer has even considered getting potential lovers to sign a "boyfriend contract".

The deal would insist the pair will never sell a story, tweet or talk about their time together.
