Tennant's shock at pants

DOCTOR WHO star David Tennant has told that the most bizarre thing about playing the Timelord is seeing his face on Y-fronts.
The Scots actor said he was still getting used to playing one of the best loved parts on television.
But he said the biggest shock was when he saw his face all over merchandise such as pants.
Tennant, from Paisley, appears on Parkinson tonight and also tells the veteran presenter about his most embarrassing acting moment, filming sex scenes in the series Casanova.
And he said of Doctor Who: "It's more than another acting job.
"It is a bit overwhelming. You go into a supermarket and your face is on a cake. There are now pants with my face on them.
"And that's not a sentence I thought I would ever say on national television."
Tennant took over the role last year when Christopher Eccleston quit.
In tonight's episode he faces the terrifying results of the Lazarus experiment, although it appears he is more scared of seeing his face on underwear.
