Charlie Sheen, Lindsay Lohan At Ease Filming 'Scary Movie 5' Love Scene

Oh, to have been a fly on the wall when "Crazy" got to pretend-bonk "Insane."

Lindsay Lohan and Charlie Sheen this past weekend to film their scenes for the comedy-spoof sequel "Scary Movie 5," and The New York Post reports the two were as at ease as as could be.

One scene Lohan shot with FX's "Anger Management" warlock had the star of Lifetime's biopic "Liz & Dick" and Bret Easton Ellis' "The Canyons" donning a submissive's collar.

"Lindsay was a great sport," one insider said, adding that she had some trepidation about poking too much fun at her image.

"She was poking fun at herself, and she really got into it and seemed to enjoy it. ... They were ad-libbing. They were joking that they've both had a lot of issues over the past couple years."

Crikey. Issues? They've had a Barnes & Noble magazine rack. They could rent out space behind a 7-11 counter. They could fill a horny 16-year-old's sock drawer.

Before "Anger Management" got a syndication-tailored episode order from FX following its freshman season, Sheen was taking "Two And A Half Men" creator Chuck Lorre and Warner Bros. Television Productions to court over his Spring 2011 firing from the CBS comedy amid a drug-and-booze relapse.

Lohan? Fresh off DUI probation, she could end up headed back to court following a July Pacific Coast Highway wreck, after which she may or may not have lied to police about whether she was driving when her rented porsche rear-ended a semi. Authorities also want a word with her about thousands of dollars worth of jewelry stolen from a friend, which Lohan was found to have possessed before it was recovered.

"Lindsay was scared by a sound effect [during filming], and actually jumped into Charlie's arms. But everything went smoothly and surprisingly on schedule," the source said.
