LOS ANGELES — Anne Hathaway and Steve Carrell certainly ooze with sexual chemistry in the upcoming movie remake of the hit series "Get Smart." But behind the scenes, things weren't so sweet when it came to their on-screen smooch.

"There was a health scare last year and a certain contact solution, I won’t say the name of it but it was the one that I use — gave you conjunctivitis," Hathaway explained to Pop Tarts while promoting her latest stint as Agent 99. "I also had a sinus infection at the same time. So I had to go up to Steve, my eye is red, puffy and dripping green — I’m just like snotty and I’m just like ... 'Come here!'"

It wasn't until after their intimate lip-lock that Hathaway discovered she had the highly contagious eye illness and had to make the dreaded call later that night to the film's producer, Alex Gartner.

"I said you might want to call Steve and let him know I had pink eye and my tears kind of got in my mouth, so he might want to worry about that," she said.

But despite the not-so sexy scenario, Carrell must have done something right. ...

"I'd do it [the kiss] again in a heartbeat!" Anne gushed.
