Actress spotted smooching Jamie Burke on beach

It would seem that dating sloppy seconds isn’t a problem for Sienna Miller.

The Factory Girl star, 25, has been spotted snuggling up on a Mexico beach with Kate Moss’s ex, Jamie Burke.

And the scantily-clad pair were all over each other like lovestruck teenagers as they soaked up the sun on holiday.

Kate Moss isn’t the only A-list star that model Jamie, 21, has stepped out with. He’s also been linked to Lindsay Lohan and Courtney Love.

Not bad for a former public schoolboy who’s barely out of short trousers.
