X17online spotted party rental trucks unloading tables and chairs outside of Irving Azoff's house, in preparation for tomorrow's big day.

Classic Party Rentals refused to divulge any deets about the outdoor ceremony and reception, but we're sure that even though it was thrown together at the last minute, the black tie wedding looks to be a lavish affair.

Let's just hope no one gets cold feet before they walk down the aisle!

Ashley may still be a full foot shorter than her super-sized man, but at least she put on a pair of killer stilettos to give her a four-inch boost at Teen Vogue's Young Hollywood party!

Ashley has seriously never looked happier. Is it the new(ish) man? The back-to-blonde hair? Or has she discovered a happiness tonic inside all of those ice-blendeds she loves?

You probably never expected to read the words "Sienna Miller" and "clean" in the same sentence, but the Broadway babe sported a fresh and natural look after a performance of her play After Miss Julie.

Say what you will about Sienna, but she's one of the most stunning women in Hollywood, even completely bare-faced!

Guess all that dry shampoo that she's supposedly peddling isn't working too well on her fried hair!

Maybe she needs to put the bleach on hold for a second and go back her natural color.

Can you imagine Heidi as a brunette?

Adding fuel to the pregnancy rumor fire, Penelope Cruz and Javier Bardem were spotted outside of an Ob-Gyn clinic in Madrid earlier this week.

The Spanish couple were seen leaving the Hospital Ruber Internacional, the exact same location where the Beckham's youngest son, Cruz, was born in 2005.

She's been vehemently denying rumors she and Javier were expecting, but with this latest news, coupled with these pix, can she really deny it for much longer?

No, not by Kristin (although she's certainly getting in good enough shape to kick anyone's ass!)

Audrina sported a pair of totally shredded pants on her way to the set of The Hills yesterday, where she shot a scene with Lo in a nail salon.

Tough life!

Apparently Hugh Hefner's twin girlfriends Kristina and Karissa Shannon do!

They told E!, "She's losing weight and she's blond now…She looks good. I want to see what she looks like naked."

There's no telling how much pull the twins have with the 83-year-old Playboy mogul, but let's hope for all our sakes' that Hef doesn't listen to 'em! I don't think I could handle even a firmed up Kelly getting her kit off in Playboy!

One of the things we love about Kate Beckinsale is that she always manages to look glam and gorge, even while picking up a box of Krispy Kremes as an after-school snack for her daughter Lily and pals!

But one of the things we love about Denise Richards is that she always looks so down-to-earth, just a regular single mom in jeans, taking care of her two daughters.

So which mom is hotter? The glamour girl Kate or the grounded Denise?
