She’s only been single a handful of days and already reports have emerged which claim Lindsay Lohan has jumped back on the dating wagon.

According to Australia’s New Weekly magazine LiLo – who split from her snowboarder boyfriend Riley Giles last week – is dating actor Heath Ledger.

The publication clams that the Mean Girls star enjoyed a number of late-night sex sessions with the Australian actor after meeting him at New York’s Beatrice Inn over Thanksgiving weekend.

“Lindsay and Heath hit it off straight away” claims a source “When she left the club she started texting him straight away and they hooked up a few times while she was still in New York. They were meeting late at night for sex. It was purely physical.”

Lohan travelled to New York with Riley – who she met at Utah’s Cirque rehab clinic in August – but speculation mounted that there was trouble in paradise after the pair were snapped partying separately.

As reported by Entertainmentwise yesterday, the 21-year-old actress ended her brief relationship with the 25-year-old in order to concentrate on revamping her career.

Meanwhile Ledger – who split from his girlfriend Michelle Williams, with who he has a two-year-old daughter, Matilda – has been linked to a bevy of beauties which include supermodel Helena Christensen.

The Brokeback Mountain star has also been spotted on the New York party circuit flirting and “making out” with a string of women.
