Katherine Jenkins - Jenkins' Nerves Over Onscreen Kiss
Katherine Jenkins was nervous about filming an onscreen kiss for an upcoming episode of cult British TV show Doctor Who - because she knew her mum would end up watching the scene.
The Welsh opera star has landed a cameo role in the annual festive installment of the sci-fi series, which airs in the U.K. on Christmas Day (25Dec10).
Jenkins was required to pucker up for a romantic shot - and the singer admits it was "the most nerve-wracking thing" she's encountered in her career.
She tells Britain's The Sun, "The kissing was the most stressful part of the whole thing. My Mum's got to watch that on Christmas Day!
"I really don't know how it's going to come across. I just want to get that bit out of the way. It was by far the most nerve-wracking thing I've ever done."
