Lisa McCune left co-star Peter Helliar stunned when she donned a merkin (a pubic wig) while filming a bikini scene for their comedy series, How To Stay Married.

Appearing on on Tuesday, the 49-year-old actress revealed she had conspired with her makeup artist, Ian, in an effort to prank the comedian. 

'I was wearing some bathers and I said to [Ian] early on in the piece, "I really want to get Pete, we have to have some hair down there so it just catches Pete's eye,"' she explained.
