If you’re going to ask Lindsay Lohan to kiss someone, make sure their mouth is perfectly clean!

The Mean Girls star recently finished up filming Scary Movie 5, where she does a bedroom scene with co-star Charlie Sheen.

According to TMZ, Lindsay wasn’t too happy about having to kiss Mr. Sheen on the mouth!

DETAILS: Charlie Sheen: “Lindsay Never Thanked Me!”

The site reports:

Sources close to Lindsay tell TMZ, she was supposed to kiss Charlie three times during their “Scary Movie” bedroom scene, but she ultimately refused to do it because of Charlie’s wild partying past.

It’s unclear what Lindsay was so paranoid about — but we’re told BOTH parties had to sign releases that they didn’t have cold sores.

Lindsay’s telling friends she warned producers ahead of time that she had issues with kissing Charlie — who’s had considerable dental work done in the last couple years — but they didn’t change the script until it was time to shoot the scene.

DETAILS: Say Word?! Charlie Sheen Tosses Lindsay Lohan $100,000!

Apparently things got so bad that they had to use a body double for some of the scenes so Lindsay could still follow the script.

Considering Charlie gifted Linds $100 grand to pay off her debt, she at least could have given him a smooch!
