Lindsay Lohan chased her ex-girlfriend around London on Wednesday night (03.06.09).

The 22-year-old actress followed DJ Samantha Ronson - who she split from earlier this year - from club to club, desperate to talk about "their future together".

Her mission began at the Bloomsbury Ballroom, where Samantha and her producer brother Mark Ronson were watching Daniel Merriweather perform.

The Ronsons quickly hailed another cab to take Samantha back to Blakes Hotel in Kensington, where she is staying. Hotel sources claim Lindsay arrived minutes later, and was finally let in to Samantha's room at 2.30am.

A source told Britain's Daily Mirror newspaper: "Short of a restraining order, nothing can ward her off. They spent a few hours together before Lindsay left with a melon-wedge grin. When we asked if she'd enjoyed her time with Sam, she just chuckled and said, 'Oh yes.' "
