I don't believe soâ€¦ I've seen a couple of Paula's earlier holiday shows where both boys were squiring a girlfriend. Jamie just decided to marry first, that's all.
I think Pa_wife hit it on the head. After all, Rachael only settled down last year, and she's my age. When you're young, successful, and your star is rising, why blow it all? Why not enjoy it? Work now while it's there -- take the time for a relationship when you've got it to spare. What with the restaurant, the shows, and gourd-knows-what-else, he probably doesn't have time for a decent relationship right now anyway.
