Married actress Jenna Elfman was left red-faced during a love scene with her ACCIDENTALLY ON PURPOSE co-star Jon Foster - because she enjoyed kissing him so much she forgot her lines.
The pair co-star in the U.S. TV comedy, about a couple coming to terms with raising a child conceived during a one-night stand.
The actress, who is married and to actor Bodhi Elfman, admits she was entranced during an onscreen lip lock - and she was shocked by how good it made her feel.
She says, "My husband and I are (sexually) active, so it's not like I'm not getting that at home. But for some reason it felt really good kissing my co-star, and I've been kissing leading men for a long time so it's not anything new. I was totally enjoying how it was feeling and completely forgot my lines."
Elfman admits she was so traumatised by her revelation, she now questions her acting ability.
She adds, "The moment I realised I forgot my lines because I was enjoying kissing my co-star, I couldn't believe it. I pride myself on being a (professional). That was the most humiliating thing."
