He continued: "She’s my best friend - I’ve known her for nine years - so I know her body language and can tell when she’s truly interested in someone, and with Joe she just seems genuinely happy.
“And as Dianne, 29, is naturally a flirty person with everyone, it’s hardly surprising they got close."
Meanwhile, the red-haired beauty has taken to Instagram to share a cosy snap of the pair with her 519,000 followers.
With Dianne pictured on Joe’s lap, the dancer said she had everything she wanted.
She captioned the post: “When I was sat on Santa Suggs lap he asked me what I wanted for Christmas?
“My response was (apart from a tamagotchi) I have everything that makes me happy already.
