We are so confused! Who is Sienna Miller dating again? First it was supposed to be 48-year-old macho-man Sean Bean, with whom she is due to start filming new Oscar Wilde adaptation A Woman of No Importance next month.

Then we heard that another co-star, Matthew Rhys was her flavour of the month, after the pair got extremely cosy on the set of Dylan Thomas biopic The Edge Of Love. Then Sienna was even blamed for the break-up between US rapper P. Diddy and the mother of his three children Kim Porter.

But now it seems a new, and oddly familiar strumpet has stepped onto the scene. Hang on a minute - it's none other than lanky Welsh actor Rhys Ifans, aka Spike from Notting Hill!

The couple were spotted lounging together as they lapped up the Ibizan sun, with Sienna even stripping off on-top in front of the shaggy haired boy. Tongues were set wagging as the twosome proceeded to walk arm-in-arm down the beach. Watch this space!
