He said: "Jen would be fantastic! I'll have her people contact the show's people. It will happen! It'd be great."
Tate - who is currently in the middle of a divorce battle with Corinne Kingsbury - split from Jennifer after the pair briefly lived together.
Following the separation, the 44-year-old actor said: "She likes top-notch hotels and luxury, and I like bed-and-breakfasts and riding my bike. That's the most shallow version of it, but it's indicative of our personalities."
Jennifer has been concentrating on her film career since leaving 'Friends', but did agree to a cameo on best friend Courteney Cox-Arquette's TV show 'Dirt' last year.
