The 33-year-old, who recently split from rugby player Danny Cipriani, was also seen leaving Jones' apartment here, reports femalefirst.co.uk.
"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," a source said.
Jones, 35, is said to be keen to make things more "serious" with Brook.
"Gethin thinks Kelly is gorgeous. He can't believe his luck, and he'd like this to become more serious," another source said.
