Roman Kemp didn't know who Sarah Greene was when they were hired to co-host 'Finish Line'.
The Capital Breakfast host had to turn to his parents, Spandau Ballet bassist Martin Kemp and Wham! backing singer Shirlie Holliman, for insider information on his 65-year-old co-presenter - who is best known for fronting children's shows such as 'Going Live!' and 'Blue Peter' in the 1980s - when he was first told they would be working together.
He told the Daily Star Sunday newspaper: “Oh My God. But it was my fault. So my mum and dad gave me a quick education.
"[They] were both interviewed by her."
However, Roman, 30, thinks the "generational difference" between himself and his 65-year-old co-host has worked well for the show.
He added: “But Sarah is so amazing and the generational difference is so nice. It created this bond between the two of us, that we were playing to two different audiences.”
Roman was left stunned by "naughty" Sarah's "dirty humour" when they were filming the show, which starts on BBC One next month.
He said: “Sarah’s naughty, man. Some of the s*** that comes out of Sarah’s mouth is unbelievable.
“She put me in my place, but sometimes I had to say to her, ‘Sarah, you can’t say that on TV!’ She’s really,
really funny and she’s got dirty humour, she won’t mind me saying that, but don’t let the pretty face fool you, 100% she knows what she’s doing.”
Roman previously detailed a spat between his mum and his godfather George Michael, who wanted to stop her moving their family to Los Angeles because it would “ruin” him and his older sister, Harley.
He told The Sun newspaper: “My relationship with fame is skewed by growing up as George Michael’s godson.
“I always remember this huge argument between him and my mum - the biggest they had actually.
“Mum said, ‘We are moving to LA,’ and he said, ‘No, that will ruin your kids’.
“He didn’t care about them, he cared about me and my sister, Harley. He was like, ‘Fame and that world is not what they should aspire to.' "
