Washington, June 5 : Megan Fox "almost cried" when she filmed a kissing scene with a man who hadn''t brushed his teeth.

The ''Transformers: Revenge Of The Fallen'' actress, who hates kissing on-screen, recalled an incident where her co-star didn''t brush his teeth before filming their love scene, reports Contactmusic.

She explained: "Oh my God! Screen kissing is f***ing gross. It''s a super intimate thing to do. Touching mouths? I have to really enjoy someone''s personality, not just their looks, before I''ll kiss them.

"This one kid I had to kiss had just eaten. And he passed a piece of whatever it was into my mouth. I swear to God. Not on purpose. Like it was in his tooth or something? And it was really salty. I almost cried. I was a b***h the rest of the day."

The 23-year-old actress also admitted that life in the spotlight is not as perfect as she hoped it would be.

She told Britain''s GQ magazine: "I grew up craving the spotlight and once it happened I immediately recoiled. It just always seemed really glamorous.

"As a child you think everyone who''s famous is very wealthy and powerful. I thought my internal issues would be solved and I would be this really confident person. And I''m not." (ANI)
