Charlie Sheen, 47, and Lindsay Lohan, 26, have a lot in common: they've both been to rehab and have had some legal troubles. But the two troubled stars, will appear together in a kinky sex scene for "Scary Movie 5."

"Charlie and Lindsay filmed a love scene," a New York Post Page Six source said. "The scene they were shooting for the movie was of them in bed together."

Apparently, Lohan had to kiss Sheen and donned a S&M collar. 

At first, Lohan was apprehensive of her "Scary Movie 5" role because she didn't want it to harm her comeback career in which she hopes to take on more serious roles. 

But once the starlet relaxed, she seemed to be having a good time. "Lindsay was a great sport," the insider said. "She was poking fun at herself, and she really got into it and seemed to enjoy it."

Sheen and Lohan will portray "the world's hottest new couple" in the movie, according to Dimension Films (via MSN). 

The two infamous actors "shared some playful pillow talk during shooting."

"They were ad-libbing," the source said. "They were joking that they've both had a lot of issues over the past couple of years."

During filming, Lohan got scared of a sound effect and "jumped into Charlie's arms."

Even though the stars are known for arriving late or not showing up at all, "everything went smoothly and surprisingly on schedule."
