So, what can we say about Diane Keaton's signature look? The giant wide leg trousers, the belt that looks like an unraveled tire tread, the too-tight tunic top buttoned all the way up, and - of course - the wide-brimmed hat to top it all off. And while we wouldn't recommend anyone trying this at home, you gotta admit - it totally works for Diane!

Diane Keaton, dressed "up" for a meeting in Brentwood...

...or Dustin Hoffman?

Hey, just cuz they're old doesn't mean they can't look good!

What's this? Diane Keaton showing a little skin? But she's usually so covered up!

Ah well - she's still gotta a fairly fine figure for a woman of 62... and at least she's not giving this face!

What a coincidence - that's the same face we made when we first saw those pictures of Jack Nicholson moobin' out on the beach!

Diane Keaton was uncharacteristically friendly to photogs in Beverly Hills yesterday, where we spotted the Annie Hall actress treating her son (yes, son) to a manicure!

But it wasn't all sugar and spice, at least the boy got his tips painted with baseballs and pokemon!

Mad Money, that is - as in Katie's new flick, which premiered last night in Westwood!

The celebrity couple took their time making their way into the theater upon their arrival, choosing to grace some of their fans with Hollywood glitz (not to mention autographs) instead of hustling inside.

That's OK - they probably knew how it ended anyway!

As you can imagine, Tom and Katie were hardly the only celebs in attendance - in addition to her Mad Money co-stars Queen Latifah, Diane Keaton, and Ted Danson, the red carpet was graced with a visit from Mary J. Blige.

It's just too bad Tom and Katie couldn't stick around for a group photo. They only stayed for 20 minutes before they cut & ran - to Tom's favorite steakhouse Cut!

They did, however, stay long enough for Katie to speak to the press about Nicole Kidman's recently-announced pregnancy. Despite their strained public relation, Katie was pure grace toward Tom's ex, telling reporters that she was "so happy" for Nicole and Keith!

There have been a lot of hat-wearing celebs out and about these past couple weeks, and we all know celebrities love their hats. Lindsay Lohan's rockin' her black cap while Tommy Lee, well, shouldn't wear yellow. On the other hand Johnny Depp looks fierce in anything while Kirsten Dunst should avoid hats altogether! (Hey, the girl could use a little sun.) Who's your fave... or actually, who's your not-so-fave?

Look inside to see our pick!

...And I'm pretty sure it's that outfit. Okay, fine, it is a little weird that Diane Keaton is wearing black clothes and a scarf - with bright red heels? - in Hollywood when it's this warm out. (I'll pretend I don't even see the hat.) But you know what? I don't care! She's still a great actress with a great figure and she can wear whatever she wants!
