Former Bond girl Gemma Arterton surprised her Prince Of Persia: The Sands Of Time co-star Jake Gyllenhaal by shoving her tongue in his mouth while filming kissing scenes for the movie.

The actress, who plays a sixth century princess to Gyllenhaal's character of the prince, couldn't help but inject some passion into their smooch despite the pair's shared understanding that their embraces would remain relatively tame, reports contactmusic.com.

"There's an unspoken no-tongues rule on set. But I got so carried away, it kind of slipped out," she said.

Arterton maintained that the pleasure was all Gyllenhaal's. "Everyone said I was lucky to be snogging (kissing) him, but he's the lucky one," she said.
