Leighton's Mom 'Threatened To Kill Me' Says Pal

The mother of Leighton Meester "threatened to kill" one of the Gossip Girl star's former pals, Radar Online has exclusively learned.

Laurel Wiig won a restraining order against Constance Meester, the actress' manager, after an ugly confrontation on January 21 in which she threatened to "hunt down and kill" and "f*ck up" the woman.

A Los Angeles judge ordered Constance, 55, to stay 100 yards away from Wiig.

"She is an addict and had made a threat to kill," Constance wrote in the court papers, obtained exclusively by Radar Online.

Constance gave birth to her daughter while doing time in a Texas prison after being nabbed in a drug ring, as the National Enquirer first revealed.

She was convicted in Georgia as part of an aunt's drug ring that smuggled thousands of pounds of marijuana from Jamaica to the United States.

Authorities said the operation netted $250 million a year.

Leighton's mom was sentenced to 10 years in prison and began serving time on August 8, 1985, while pregnant with the future TV star.

Michelle: "I Don't Know Anything About Weed"

When it comes to marijuana, Michelle Trachtenberg just says no. So when longtime pal Topher Grace asked her to play a pothead in his upcoming 80s flick, Take Me Home Tonight, she had to study up.

"I play a goth stoner chick and I don't know anything about the weed," the Gossip Girl star, 25, told Us Magazine Tuesday at a fete celebrating her recent Maxim cover. "Really, I know nothing about it. So I had to do a little research."

The actress was quick to add her research didn't involve actually lighting up, just chatting up a few pals.

"I was talking with my friends, who are apparently a bunch of f--king stoners," she told Us.

The prep work for her Maxim cover was a bit more rigorous.

"I stopped eating," she joked of donning lingerie for the shoot. "No, I ate a lot. My favorite foods are bread and cheese, so I basically just limited eating those things from fives times a day to about twice a week. But only for ten days."

And post shoot? "Immediately after I wrapped on set I asked, 'Who’s ordering the pizza?'"
