The star – recently linked to model Jamie Dornan and shipping heir Stavros Niarchos – was spotted smooching singer Jamie Burke on Sunday.
In fact, the 19-year-old actress (in New York City to promote her upcoming films Just My Luck and A Prairie Home Companion) has been spending lots of quality time with the British-born bartender, 21, who briefly dated Lohan's friend Kate Moss, 32, in January.
Last Thursday, the twosome partied hand-in-hand at Manhattan's G-Spa, and on Saturday Lohan attended Burke's band's performance at Delancy Lounge.
"They are not serious," says one friend, adding that Lohan and Burke first met at a New York City club about three months ago. "But he's sweet and loving."
Lohan's rep had no comment on the relationship.
Could this put a damper on Lohan's friendship with Moss? The two were last seen pole dancing together at Scores strip club on Jan. 11, not long after Moss and Burke returned from a romantic ski trip to Colorado.
