Tulisa Contostavlos might have The X Factor but Cara Delevingne has her ex!

Tulisa Contostavlos might end up having some serious beef with Cara Delevingne if rumours of the model’s latest beau are true.

The bisexual fashion star is reportedly dating former Skins actor Jack O’ConnellTulisa‘s former flame. Cara, 22, and Jack, 24, met on the set of new film Tulip Fever and apparently the duo have been casually seeing each other.

Although they’re not taking things too seriously, Cara is said be a ‘big fan’ of Jack and maybe he developed a liking for her too after catching a glimpse of her first ever sex scene.

Cara films the saucy clip in the historical 17th Century flick with, um, Matthew Morrison from Glee aka Mr Schuester.

Next thing you know she and Jack hit it off and she’s been wearing a Derby County football scarf because that’s his team. Aw!

Maybe she heard reviews from Tulisa – who was going out with Jack in 2012 – that his sexual shenanigans once caused an earthquake in Bulgaria. While the rest of the world is not sure how reliable that information is, perhaps Cara wanted to find out for herself.

Before Jack, she was in a brief relationship with American actress Michelle Rodriguez but they called it quits in May.

Meanwhile Tulisa has revealed she is totally single after splitting from her multi-millionaire man Costas Panayiotou following a summer romance.

The 26-year-old former X Factor judge has since been hanging out with her ex-boyfriend Fazer – fellow N-Dubz member – making sweet… music in the studio.

She also appeared back on our screens last weekend helping out Louis Walsh as he picked his acts for the groups category on ITV show The X Factor.

We have a feeling Tulisa might let her new tunes do the talking. But maybe Cara will too as apparently Nicki Minaj has been giving her tips to launch a music career.

Watch out Tulisa, she could be after your Female Boss crown!
