'Call Girl' star found Piper kisses 'awkward'

Secret Diary Of A Call Girl star Callum Blue has admitted that he felt 'awkward' when he filmed kissing scenes with Billie Piper.

The new series of the ITV2 drama sees the actor playing Alex, a clean-living doctor who starts a romance with Piper's character Hannah.

As the chemistry heated up between the two characters, in real life Callum struggled to stop thinking about Piper's marriage to Laurence Fox and recent pregnancy.

"Billie and I had just met and it's so weird kissing someone you've just met - especially when they've just got married and they're pregnant at the time," Blue told Hot TV magazine. "I mean it's uncomfortable anyway, but add in those two factors and it's pretty awkward to say the least!"

Asked about the show's nude scenes, he replied: "I was always scared of nudity and sex scenes, but last year I was in a movie where I was completely naked the whole way through. That experience was terrifying at the beginning, but once you're naked you're just naked and nobody gives a s***.

"This show was really easy for me - there was only one day where I was completely naked on set and then it wasn't so bad because I'd done it before."

Secret Diary Of A Call Girl returns to ITV2 on Thursday at 10pm.
