It's believed Tre was planning on getting down on one knee after the turkey, but his plans have been cut short.
A source told The Sun newspaper: "Tre called Joan and said he wanted to propose to Cheryl when they are in America with his parents."

"He wanted to do it on Christmas Day, but Joan refused to give her blessing."

Even if they do seem ridiculously loved up.
The source added: "She's warming to Tre but there's no way she's going to let another man take Cheryl down the aisle so quickly."
Cheryl of course famously divorced footballer Ashley Cole in 2010 after six years together.
"Tre's got his work cut out if he thinks he can get around Joan so soon."
Cor, this one sounds like a tough cookie but we reckon if any man can melt her, it's sure to be Tre! We just hope he is up for the challenge.
