Lindsay Lohan Does Cocaine, Calum Best

Lindsay Lohan does cocaine? No shock there.

Lindsay Lohan sleeps with a hunky British guy? Also no surprise on that one.

But the unexpected news making the celebrity gossip rounds this morning is that we're not solely referring to Jude Law here.

While Lindsay has shagged the heck out of that actor, she's currently involved with a different English chap: some TV personality named Calum Best.

At a party at New York City hot spot Tenjune Wednesday night, Lohan was spotted with Best as she celebrated her new cover of Nylon magazine.

The duo was seated with Lindsay's attention-starved and awful mother, Dina Lohan, along with a few friends in a private banquette by the DJ booth. Reportedly, Lohan sat next to Best all night (when she wasn't up dancing to Eminem or air kissing VIP well-wishers, of course).

Just after midnight, Lohan and Best â€" who spent time together in London last fall and also kept close company while out on the town the previous night â€" shared a very discreet kiss. But not discreet enough for certain celebrity gossip mavens not to catch them!

After smiling as DJ pal Samantha Ronson spun Amy Winehouse's "Rehab" and posing for a quick photo with her mom and Best, Lohan focused again on the man a number of friends referred to as "her new boy toy," at one point leaning in for a 30-second smooch.

These two crazy kids were first linked by the British tabloids last summer, and were spotted hitting the London nightlife scene in the fall after Lohan was a presenter at the World Music Awards there.

Meanwhile, Lohan also spoke to David Letterman Wednesday about pal/enemy Paris Hilton's jail sentence ("It's terrible") and her troubles while filming her new movie, Georgia Rule.

"I was out too late a few of the times. I had a boyfriend. I was fighting with him," she said. "I was very immature. I was very irresponsible. And I understand that."

Doesn't mean she has any changes to change it, of course.
