Strictly Come Dancing pair Denise Van Outen and James Jordan have a 'natural chemistry'.
The pair topped the leaderboard at the weekend after an energetic jive earned them 32 points from the usually hard to please judges.
And the duo's relationship has got everyone talking backstage, but insiders insist that there's no jealousy from Denise's husband Lee Mead.
A Strictly insider revealed: "They get on like a house on fire. But Denise puts it down to their natural Chemistry.
"She says Lee isn't jealous at all."
Denise meanwhile recently admitted she had struggled dancing close to James, claiming she often feels like she wants to kiss him!
She said: "It's so weird dancing to a man this closely. I think the only times I've ever been with a man like this is when I've been trying to go in for a cheeky snog!"
Strictly Come Dancing 2012 continues this weekend with the third live show. Johnny Ball became the first celeb to be eliminated last Sunday, and this Sunday will see another star get the axe!
