Dun dun dun! We've heard rumors that these two were on the rocks for quite some time now, but we certainly haven't seen them do something like this before!

Last night, Deryck Whibley and some male pals arrived at MyHouse around midnight, and he left around 12:50am. When asked where his wifey was, the Sum 41 frontman remained totally silent. Normally we'd just leave it at that, but guess who showed up within minutes of Deryck's departure?

Yup, just before 1am, Avril Lavigne traipsed right into the Hollywood hotspot with...Brandon Davis?! Ew! And that's not even the worst part - our photographers spotted Avril sitting in his LAP when they left in a limo later.

We're not sure why Deryck and Avril would go to the same club at different times, but Avril hanging out with Brandon Davis? I know he's a mutual friend of both Paris and Av, but if I was Deryck, I'd be livid!

Think they're headed towards divorce, or did Deryck simply need a night away from his lady?

Ahh, here we go again!

Paris Hilton and Doug Reinhardt have taken yet another tropical vacay (um yes, we're jealous!), and even though Miss P is posting love dovey pics all over her Twitter page, she won't reveal their location! Aww, c'mon Paris! I guess it must be nice for her and Doug to have the island to themselves though!

The heiress and her hunky bf have been sunning themselves, golfing and watching movies -- yeah seriously, we want her life!

The always fashionable Nicky Hilton is known for wearing lots of black, white and grey, but yesterday she paired her basic denim shorts with a bright plaid button down, and we're lovin' it! Maybe she's finally given in to our pleas for her to wear more colorful clothing?

Hint: It's not Jessica Alba!

The actress and her adorable daughter went grocery shopping in Bev Hills yesterday afternoon, and much to our surprise, Honor was the one flirting with the cameras! Though both of her parents are notorious for being grumpy with the paps, they have been nicer lately, so maybe that's rubbed off on the little celebritot?

Last night, Amy Winehouse had to cut short a comeback concert in St. Lucia due to rain, and surprisingly, concertgoers didn't seem to mind.

Amy performed for about an hour at the St. Lucia Jazz Festival on Friday, and her spokesperson said in a statement, "Amy is very disappointed as St. Lucia has been wonderful to her and its people have welcomed her with open arms, but circumstances beyond anyone's control meant that this special show did not go as planned."

During the hour-long set, Amy forgot her lyrics, accidentally flashed her underwear, and even muttered to the audience at one point, "Sorry, I'm bored." Several fans spoke with the BBC about the incident, and one said, "It was disappointing...it is very sad to see, but she is obviously not fit to be on stage."

Yikes! So why was she even performing in the first place?

He's up against Reynolds and Gosling, but after looking at these shots of the hunky dad, he might be taking over the number one spot! Ryan Phillippe was snapped riding his motorcycle yesterday afternoon (and later picking up daughter Ava), and we're drooling. Abbie Cornish is a VERY lucky lady!

Jennifer Aniston is back to work on The Baster set, and we had a little case of deja vu...didn't she just wear this sexy red dress last week? Ahh, the joy of reshoots. I mean, did you really think Jen would step out in a backless dress if it wasn't for a movie role? We all know she's more comfy in her uniform of jeans and a t-shirt.

Speaking of shooting, when are they gonna wrap on this thing? Jen's been basting away for what seems like an eternity!

Sure she's wearing glasses here, but maybe she's having trouble seeing things in general, because I can't imagine why she'd pick out an outfit like this. Okay, the pants and flats are fine, but what's going on with this top?! The nude piece of fabric on the back? Katie, we love you, but uh, please don't ever wear this fug shirt again.

Mrs. Tom Cruise went shopping at Maxfield yesterday, and we're really hoping she invested in a few vibrant, spring-y pieces...this drab outfit has got to go!
