Anne Hathaway gave Steve Carrell pink eye when they kissed in new movie Get Smart.

The 25-year-old beauty - who stars as Agent 99 in the spy comedy - said she was suffering from itchy eyes when she filmed a particularly raunchy scene with her co-star Steve.

She said: “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. 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 snotty and I’m just like 'Come here!' "

However, Anne revealed she was unaware she had pink eye - more commonly known as conjunctivitis - and was forced to ring the film’s producer Alex Gartner to warn him.

She added to Fox News: "I told Alex, ‘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!’

“But I'd do the kiss again in a heartbeat!"
