CSI: Crime Scene Investigation star George Eads is engaged to marry his longterm girlfriend.

The actor has been dating Monika Casey for close to six years and decided to propose to her after she helped him through a difficult summer, which saw Eads undergo surgery to fix his broken spine.

Breaking the news on The Late Late Show with Craig Ferguson on Monday, the actor said, "I got engaged actually to a really nice girl.

"When you go through something that terrible together... I don't know, maybe it happened for a reason. She really was my champion and really helped me get through that."
