Tulisa Contostavlos has apparently split up with Skins star Jack O'Connell because of their conflicting work schedules.
The X Factor judge flew to Bulgaria last week to see her actor beau and ended their three-month relationship, the Daily Mirror reported.
An insider told the newspaper: "Jack is filming the new 300 sequel in eastern Europe and will be there until November. He isn't able to travel to the UK at all, as filming schedules are so tight... A long-distance relationship just wasn't working."
The couple are said to have come to the decision together after talking over dinner.
But Tulisa was all smiles on the red carpet for yesterday's X Factor auditions in Newcastle, in a striped Vivienne Westwood frock.
She was joined by new judge Nicole Scherzinger, who admitted she'll have less time with her racing driver boyfriend Lewis Hamilton while she appears on the ITV1 show.
"I'll be spending less time with him as I believe the shows will run at the same time as his races. It'll be great to be in the UK but the most important thing is the contestants."
