The "Flipping 101" star joined "TMZ Live" Thursday, and said, yeah ... he's down to walk that familiar path again of shooting a TV show with his spouse. He told us Heather -- who's on the Netflix show "Selling Sunset" -- tends to be with him nearly 24/7, anyway, so why not do a show with her?
To their immense credit, they not only remained friends but also costars. That being said, Tarek says shooting a show as spouses did NOT lead to their divorce ... so he's not worried about working with Heather.
Christina, of course, has more than moved on. She and Ant Anstead welcomed a baby boy a little over a year ago.
As for Tarek ... he and Heather have been engaged for 2 months now, and their wedding's pretty much planned out. Except for one not-so-tiny detail.
