Lindsay and Calum's beach romp

The Mean Girls star showed of her buff body in a teeny bikini

Lindsay lohan romance with lothario Calum Best has gone into overdrive.

Two weeks into their rekindled romance - which has already seen Best meet Lohan's mother Dina - the pair have slipped off for a romantic getaway in the Bahamas.

Frolicking along the beach, the loved up couple could barely keep their hands off each other.

Lohan, 20, squealed with delight as they splashed around the water, and stole kisses and cuddles from her new man.

At one point, she did find herself a little overexposed as her bikini top slipped down, giving onlookers an eyeful.

The couple were in the Bahamas to attend a VIP party at the exclusive Atlantis Hotel.

Signs might be pointing to a serious relationship, but even Best's agent isn't convinced it will last.

Best's spokesperson Dave Read told The Sun: "Calum and Lindsay get on really well together. But this is Calum. We’ll have to see."

Best, 26, is notorious for his heart-breaker ways - he's been linked to model Kimberley Stewart, Jodie Marsh and Girls Aloud bombshell Sarah Harding, among others.

But Lohan is not to be outdone - her rumoured love interests include James Blunt, Robbie Williams, Jamie Burke, and Paris Hilton's former flame Stavros Niarchos.

Lohan and Best first met in London last November when she was in town to host the World Music Awards.
