Singer is very complimentary about the comedy star
The Doctor Who star now understands why the newly-engaged Little Britain actor has always been such a hit with the ladies.
‘He did show me his penis quite recently,’ Billie reveals.
‘It was wonderful. Seriously, it’s not bad. No wonder he feels quite sexually confident. He’s packing it’.
Billie, 27, is married to actor Laurence Fox, 30.
