Lindsay Lohan is taking a break from chasing boys and plunged into a hot and heavy romance with her lesbian DJ pal Samantha Ronson, sources tell Star magazine. “They are lovers,” claims one insider. “The rumors about them hooking up are totally true. Lindsay is trying to be low key about it, but everyone knows that they are way more than friends.”

Earlier this month, while in Japan doing a photo shoot, Lindsay was spotted by a source locking lips with Samantha in a Tokyo nightclub. “They just started making out right there like they didn’t care who saw them,” the source tells Star. “Maybe because they were across the globe, they didn’t think anyone would notice.”

The pair was also spotted sharing a long, passionate kiss and groping each other at least once before, at New York City hot spot The Plumm. One source tells Star that Lindsay described her relationship with Samantha as an “on-again, off-again” romance, which has been going on since last year.

"Lindsay said they were lovers,” the friend claims. “She said, ‘We hook up all the time!’”
