Melissa and Jenny McCarthy
Talk show host Jenny got Melissa one of her first jobs on a show she was working on, and told People about helping her with her career. "There is a crazy story going around that I once told my cousin, Melissa, that she would have to lose weight in order to get into show business," she said. "Nothing could be further from the truth. When she was starting out, I was fortunate enough to be in a position to get her a job on a show I was doing, to learn the ropes and get some experience on a TV set in front of the camera and behind the scene. She has accomplished everything she has accomplished through hard work and her extraordinary talent, and I've only ever encouraged and supported and wished her the very best."

Jamie Redknapp and Frank Lampard
Jamie is the son of football manager Harry Redknapp, who incidentally is also an uncle to Frank Lampard. The pair have both played under Harry while at Southampton and West Ham United respectively.

The pair have played many matches against one another
Cath Kidston and Kirstie Allsopp
