Michael J Fox? He is cute as a button.

No.
Hint .. he's in a TV show.

What type of show? Comedy, Drama?

Drama, Sunday night 10 pm, CBS, male, actor ( movies and tv ), 43 years old, Australian, married, 3 children.

Sorry even that doesn't help me. Don't stay up past 9pm and the wife watches dramas. Don't google answers so it would appear I am out

He was in " The guardian " ( tv show )
Movies ... L.A. Confidential, The devil wears Prada, Margin call.

P.S. I don't stay up late either but I tape the show ... like I said I would like to take him home. lol !!

Adrian Grenier?

Nope. If you guys can't guess it now with all those hints you never will.
Metallica you can give a new quote if you wish since H2O did it last.

Simon Baker? If not, only 1 other guy from Prada that I can think of.

Yes.

"We do look very different, we're older. You know, he's fatter now, I'm thinner. It's true though."

Abbott and Costello?

Awesome guess but wrong.

Hint #1: Actors.
