The Mirror newspaper claims that Chezza, 29, and 27-year-old Tre have been rehearsing together in Los Angeles this week - and are looking forward to seeing a lot more of each other in the near future.
A source said: "She's really into him and taking him on board as a backing dancer on the tour was the perfect way for them to spend all their time together.
"During her marriage to Ashley Cole, they had to spend a lot of time apart due to her commitments and his football matches. But this time around, she’s taking no chances. She wants to see if it's something special and after four months together, she's excited about where things are heading.
"Nicola Roberts and Kimberley Walsh have met him and loved him – so she's got approval from the other girls."
There is even speculation that Tre could also be hired for the Girls Aloud reunion tour - which is tipped to happen early next year.
Chezza has been linked to dancers before of course - namely Derek Hough - but the Mirror's source reckons there's a lot more potential with Trezza than there was with Dezza.
The source continued: "Cheryl's really into Tre. It's far more serious than it ever was with Derek.
"Tre's really winning her heart right now and she's excited about it all. She's thrilled to be spending so much time with him and hopes it cements them as a couple."
