The pair have been spotted on a date in LA, and Kelly is said to be growing close to the former 'Blue Peter' presenter, whose engagement to opera singer Katherine ended in December 2011.

According to The Mirror, Kelly was also spotted leaving Gethin's apartment, where he has been living whilst trying to find US TV work.
A source told the paper: “They have fancied each other for ages but have never been single at the same time before. Kelly thinks Gethin could definitely be boyfriend material."
“Gethin thinks Kelly is gorgeous. He can’t believe his luck, and he’d like this to become more serious," another insider added.

Kelly was left heartbroken and embarrassed earlier this year when Danny Cipriani reportedly cheated on her, just months after they rekindled their romance.
She has since been linked to David Beckham's best friend Dave Gardner, and Lawson frontman Andy Brown.
Recent reports even suggested that Kelly was close to a reunion with another of her exes, Thom Evans, after he split from '90210' star Jessica Lowndes.
We're guessing he wasn't aware of a certain Mr Jones being on the scene too.
