All dolled up as Mr. and Mrs. Scarecrow, Alyson Hannigan and hubby Alexis Denisof held on tight to their little pumpkin Saytana as they headed to a Halloween party, before taking part in some neighborhood trick-or-treating, in Brentwood.

The How I Met Your Mother star outfitted her darling 2-year-old in an adorable Jack-O-Lantern costume, complete with matching candy pail, black tights and orange Crocs.

What a sweetie!

While we were shocked that Kim Kardashian filed for divorce from Kris Humphries so soon (she was married to the NBA star for just 72 days!), it doesn't come as a total surprise given the recent rumors that their relationship was on the rocks. The photos of Kris flirting with a mystery brunette in Miami may have had something to do with the split, but it seems as though his love for Kim's money was ultimately what led to the crumble of their marriage.

A source who travelled to Dubai with Kim earlier this month tells X17online exclusively:

"I heard Kim on the phone with Kris at one point during the trip, and she was swearing and screaming at him about how he doesn't have anything going on and how she's not going to support him."

The source added that the constant feuding was a huge source of stress for Kim, and interestingly enough, this isn't the first time Kris has been criticized for going after Kim's money. During the wedding episode of Keeping Up With The Kardashians, Kim's sister Khloe voiced her concern on the matter, saying she was "worried about Kris' intentions," adding that he "has nothing to lose if he marries Kim and gets a divorce."

Kris has a $9.6 million contract with the New Jersey Nets (he made $3.2 million in 2010), but Kim and her family earned a whopping $65 million in the same year, so she has far more at stake financially. Of course, the reality TV starlet has hired a high profile divorce attorney to handle her case, and her rock solid prenup reportedly leaves her with just about everything, so it sounds like her troubles will be over soon enough...

Our photogs caught up with Brittny Gastineau at LA's famous The Grove shopping center on Monday (above), only hours after news broke that Britt's bff Kim Kardashian was filing for divorce from her hubby of just two months -- NBA player Kris Humphries.

Tres Glam jewelry designer Gastineau stood by Kim, telling us:

"I'm sad for them [Kim and Kris], but Kim is a strong woman. Sometimes things don't always work out the way we planned."

Just a few minutes later, Gastineau Tweeted: "Some girls don't realize what they're worth, some guys don't realize what they have."

Just last week, Gastineau told us that no matter what happens, "Kim will be fine." She would not confirm nor deny a break up at the time.

Christina Aguilera and Jordan Bratman were spotted picking up son Max from school on Monday, and the celebritot was decked out in an adorable chain mail costume. Aw, looks like someone's ready to get their trick or treat on tonight!

Xtina got into the holiday spirit with a skeleton sweatshirt, but we're wondering if she's going to get all dressed up and collect candy with Max or if Jordan is on Halloween duty while she hits the Hollywood party scene later tonight ...
