We guess they really are best friends!

Despite announcing their separation last week, estranged couple Hilary Duff and Mike Comrie were spotted driving together in Mike's SUV after a family brunch on Sunday. We don't know how they do it -- but we are impressed that the duo can remain such good friends in lieu of their split!

On Friday, the former Disney star and the retired hockey player announced they had split after three years of marriage.

"Hilary Duff and husband Mike Comrie have mutually decided to an amicable separation. They remain best friends and will continue to be in each other's lives. They are dedicated to loving and parenting their amazing son, and ask for privacy at this time," her rep said in a statement.

The former lovebirds wed in August 2010 and welcomed son Luca in March 2012.

Break out the blue! Olivia Wilde and Jason Sudeikis are expecting a baby boy.

The pregnant actress chatted with People Magazine last night at the 2014 Golden Globe Awards, and she revealed that she'll be giving birth to the couple's first son at the end of April.

Wilde showed off her baby bump in a sparkly green Gucci gown, and joked to Ryan Seacrest, “It’s great — I’ve never had boobs before! Until about a week ago, I just looked fat! I wanted to be like, ‘I’m not fat, I’m pregnant!’”

Wilde and Sudeikis have been together since 2011, and they got engaged in January of 2013.

While many of their contemporaries were busy in the pre-Golden Globes melee on Sunday morning -- hands-on Naomi Watts and Liev Schreiber spent some time with their sons! The longtime couple took their sons out separately on Sunday to run some last-minute errands before they hit the red carpet at the 71st Golden Globe Awards.

The 45-year-old Australian actress and five-year-old Sam took a trip to the Brentwood Farmers Market. Dressed in work-out gear, the Diana star showed off her trim figure with a Nike top, cropped black leggings and running shoes. The Adore star looked very low key with no make-up and covered up her blonde locks with an olive green basbeball cap. Her tow-headed son played on his scooter and wore blue shirt, khakis, a grey sweater, gym shoes and helmet. Safety first!

Meanwhile, Ray Donovan's star, who was wearing his heart on his chest, spent time with the duo's six-year-old son Sasha. The father/son team picked up some essentials at Target. Sasha was quite the little helper, holding on tightly to a roll of wrapping paper.

While Naomi wasn't nominated and Liev didn't win for his role on his Showtime series -- at least they got in some no-fuss time with their wee ones.

Whether it's clothes or cars, Kristen Stewart likes 'em old and dirty!

Over the weekend X17 photographers snapped K. Stew tooting around town in an old Isuzu Trooper, and she was driving back to her Los Feliz pad from Malibu. The 23-year-old starlet hung out in Malibu with several pals earlier this month, and since she bought a home in the 'Bu in 2011 for $4.8 million, it sounds like she's got a nice place to crash! It was reported that she bought the place for her mom, but we're thinking it's usually vacant...

K. Stew will be heading to Utah in the next week to premiere Camp X-Ray at Sundance, and despite the fact that she's been busy with friends and work, a source tells HollywoodLife that she's still talking to ex-boyfriend Rob Pattinson. "They have been staying in touch, sometimes they Skype or text each other," a source tells the site. "They are both going to be really busy soon. Kristen prefers it when she’s busy working, and she’s excited to go to Sundance."

Think these two will hook back up in 2014?

We can't tell a lie -- we were pretty shocked to see Lamar Odom's face at Diddy's Golden Globes party last night at 1 OAK in West Hollywood. Despite substance abuse problems, the disgraced basketball player was looking rather spiffy in a tux at the award's show after party. Celebs like Joaquin Phoenix, Christina Milian and of course Diddy himself, were also in attendance at the glittering soiree.

While Lamar looked like he was in good spirits -- we wonder what Khloe thought of seeing her estranged husband out on the town?

It's been a rough year for the former Clippers player. The 34-year-old was arrested on charges of driving under the influence on Aug. 30, 2013. After months of rumors about drug abuse and cheating allegations, Khloe, filed for divorce and legally changed her last name back to Kardashian on December 13, 2013.Just last week Khloe and Lamar are officially listed their massive martial home in Tarzana, Calif., for $5,499,000.

Despite some major issues -- Lamar looked in fine form last night. Hopefully he's headed back on the right track.

Kylie and Kendall Jenner attended Lil Twist's 21st birthday bash at Philippe in Beverly Hills on Saturday night, and the ladies might not be of legal drinking age, but it looks like they still had a blast celebrating! (And check out those bottles of wine behind the girls ... totally the right place for a pair of teenagers to be!)

The ladies arrived around 9pm, and it seems as though they were chaperoned by Scott Disick, though he wasn't in any of their Instagram pics. "Our lil boy ain't so lil anymore @liltwist," they wrote. The group dined on Twist’s favorite menu items including chicken satay, vegetable spring roll, Beijing chicken, salt and pepper lobster and spicy prawns and Lil Twist sipped on Myx sparkling wine. The group left around midnight, and Kylie later posted the pic below and wrote, "happy birthday to my best friend" ... wait, so they're just friends now?

Yikes!

Woody Allen's son Ronan Farrow didn't exactly approve of the tribute given to the director at last night's Golden Globe awards, and decided to share his opinions on Twitter, even accusing the 77-year-old Hollywood legend of molestation!

"Missed the Woody Allen tribute - did they put the part where a woman publicly confirmed he molested her at age 7 before or after Annie Hall?" the 25-year-old tweeted.

Farrow is referring to an incident where Allen was accused of inappropriately touching his then 7-year-old adopted daughter Dylan. The little girl's case was never tried and charges were eventually dropped.

It has long been believed by the public that Ronan was Allen's only biological son with Mia Farrow, but the Rosemary's Baby actress recently confessed to Vanity Fair that her son could have actually been fathered by first husband Frank Sinatra!

Talk about a dysfunctional family!

It's Miley and Mary Jane!

Over the weekend Miley Cyrus took her boxer mix for a walk in the neighborhood, and though she looked great in a pair of leggings and sneakers, she seemed a little bummed! Not nearly as sad as she looked in her Marc Jacobs ad, but we wish she had cracked a smile ... or at least stuck out her tongue!

Despite her somber appearance, the 21-year-old starlet tweeted, "I love being alone on sundays," but on Saturday she wrote, "I get called an ugly lesbian a lot more than one would think. Or maybe not. Can u atleast call me an interesting lesbian. I hate the U word."

Aww, Miles! Cheer up buttercup!
