Hilary Duff Mike Comrie scarf hat jeans boots uggsHilary Duff and Mike Comrie are one of those couples that just seem oh-so-boring.

I know that sounds like a diss, but in Hollywood, that's a huge compliment, because it means their relationship is probably rock solid!

Here's the cute couple spending father's day together in LA. Now, it's no secret that Hil doesn't have the best relationship with her own father, but does her incredibly stable relationship with Mike mean she's ready to make him a father soon?

Their kids would be so cute...and would probably have the biggest upper-arms on the playground!
