THESE days it's a full time job just trying to keep up with Britney Spears' love life.

The pop princess - whose on-off romance with Justin Timberlake has hardly been out of the news - caused even more jaws to drop when she tunred up to the Hollywood premiere of The Recruit.

Cameras were poised to catch Spears with expected date, Limp Bizkit's Fred Durst.

There was some surprise, then, when Ms Spears sashayed in on the arm of... one of the film's stars, Irish actor Colin Farrell.

Britney, love, I know its a woman's prerogative to change her mind but this is getting silly.
