Jim is better looking and very attractive. There's a reason he snapped up a beautiful model so quickly. This new guy isn't cute. Let's face it, Tanya is hiding him. I think their personalities are pretty much the same, obviously I don't know them personally.
Isn't it funny how our personal taste can differ so much - I've always thought of Jim as quite rat-faced, somewhat effeminate, pinched and mean/sneaky looking. This was before knowing anything of his personality (just seeing the odd photo of him). Knowing his personality a bit more now, I still find him very unattractive.
I would have said until close to the end of their marriage that Tanya was definitely the more attractive member of their partnership. Nowadays, I'd say they're pretty much on par with each other.
I can't remember Jim's fiancèe's name but I wouldn't describe her as a "beautiful model". I'd say she's a fairly standard pretty girl.
Tanya's new bloke is very ordinary looking but on the more attractive side of average, to me. He has a kind face, too.
I have to admit, it makes me smile to see all the comments critiquing Tanya's choice of man based on his height - like me, she's quite a short lady, nearly everyone is "tall" to her!
