Gwen Stefani was snapped at the Jonathan Ross Halloween party in London on Wednesday night, and we're still not sure what she was, but she looked amazing. Seeing as she has a fake gash on her head and a slit throat, that's saying a lot!

Gwen and her family are currently enjoying some time in the UK before she goes on tour with No Doubt in late November, and she arrived at Heathrow Airport on Wednesday morning with her youngest son Zuma, joining hubby Gavin Rossdale and their oldest son Kingston.

Ashlee Simpson is giving us a sneak peek at her new "Bat For A Heart" music video, and this is also the first song she's released in four years. We can't believe it's been 8 years since she burst onto the scene with her debut album, Autobiography!

“Happy Halloween! As promised, here’s a little tease of what’s to come!” Ashlee tweeted. “In this tease I do drop the F bomb so you’ve been warned!”

The 28-year-old singer/actress shows a lot of skin and looks like a hot mess in some of the shots, but she still looks pretty sexy. But how's the sound? You tell us! We're reaaaally curious as to what the rest of the video (and her forthcoming album!) will be like!

Rather, Jessie from Toy Story took an adorable little Buzz Lightyear trick-or-treating on Wednesday evening!

Sandra Bullock and her 2-year-old son Louis were snapped on Halloween, and it looks like the two had a blast parading around with the other parents and kiddos in costumes.

It's hard to believe the 48-year-old Oscar winner/doting mom made the news earlier in October when she appeared totally naked in a promotional video for pal Chelsea Handler! The clip started off with the two ladies in the shower sans clothes, and Sandra proceeded to tell her pal that she needed to worry about “pulling her sh*t together," adding, "You have a responsibility to be a role model -- a role model to young girls and gay and questioning youth. And you need to lay off the booze. Lay off the booze. Lay off the booze!" And it got even worse after that, with references to female anatomy and more obscenities. Hey, anything for ratings!

Actors Evan Rachel Wood and Jamie Bell tied the knot in a private ceremony on Tuesday in California, her rep has confirmed.

The True Blood starlet wore a custom mermaid gown by Carolina Herrera, and the designer told Us Weekly, "I am so happy for Evan, she is a timeless beauty and her gown in Chantilly lace captures this perfectly."

The pair met in 2005 on the set of Green Day's "Wake Me Up When September Ends" music video, and after a year of dating they split, only to get back together in 2011. Bell proposed in early 2012, a little less than two years after Wood called off her engagement to rocker Marilyn Manson.

This is the first marriage for both stars ... Congrats!

Black leather pants? Check. See-thru blouse? Check. Black bra exposed? Check.

Kim Kardashian definitely knows how to put a revealing look together ... or maybe her sexy beau Kanye West did the honors.

The twosome walked hand in hand while heading out to lunch in Miami. Joining the power couple ... sister Kourtney and her baby daddy Scott Disick.

Kim or Kourtney have been busy filming Kourtney & Kim Take Miami which will premiere next January. We can't wait to see the drama unfold!

After hitting the gym almost every day for the past few weeks, Vanessa Hudgens and her little sister Stella put on some cat ears and headed out the door, and it looks like the ladies had their bags packed for a Halloween party!

Yesterday Nessa gave us a sneak peek at their outfits, as she posted the above pic on her blog and wrote, "It’s here! Halloweeeen!!! Last night I was a cat. A kitty cat!! Like??" Hmm, so does this mean that the Hudgens sisters have yet another set of costumes planned for tonight?

How amazing does Jen G look these days?! Hot mama!

Jennifer Garner stepped out in Santa Monica yesterday to run errands and grab lunch at Toscana, and the mom-of-three has officially dropped all the pregnancy pounds... and then some!

Ben Affleck's wifey looked super skinny and toned in dark denim, which she paired with a blush colored sweater and loafers. These days, celebrities are pressured into dropping the baby weight in record time after giving birth, but the Valentine's Day star took her time and appears to have done it the healthy way!

The brunette beauty gave birth to son Samuel back in February and had no shame stepping out in public looking less than perfect shortly after, unlike some other Hollywood starlets - ahem, Jessica Simpson!

A hot body AND tons of confidence?! Talk about sex appeal!

We're not sure where mom Jessica Alba was, but on Wednesday afternoon we snapped her daughter Honor and the nanny doing a little pre-trick or treating in Los Angeles.

Of course, we had a little case of deja vu ... it turns out Jess and Cash also dressed as the Incredibles over the weekend:
