Looks like a little cardio was all she needed to cheer up!

On Saturday Maria Shriver was spotted leaving her spin class in Brentwood, and Arnold Schwarzenegger's ex-wife was in a great mood after her workout. Ever since Arnie started making media appearances to promote his new book, details regarding his cheating scandal and the child he fathered with the family's housekeeper were thrown back into the spotlight, so we imagine poor Maria has been beyond embarrassed.

Of course, the former California governor still seems to think that things can be worked out between the two of them. In his new autobiography, Total Recall: My Unbelievably True Life Story, he writes, "The public nature of our separation makes it doubly hard for us to work through it. The divorce is going forward, but I still have the hope that Maria and I can come back together as husband and wife and as a family with our children. You can call this denial, but it's the way my mind works. I'm still in love with Maria. And I am optimistic. All my life I have focussed on the positives. I am optimistic that we will come together again."

Hmm, but is she?

After a brief trip to New York City, Jessica Alba is back in Los Angeles, and on Saturday she was on a mission to do one thing: go pumpkin picking with her family!

Jess and husband Cash Warren took their daughters to the Pumpkin Patch in Brentwood, and the 31-year-old actress bonded with baby Haven while her hubby hung out with Honor, taking the 4-year-old for the ride of her life down the slide. And that butterfly face paint? So adorbs!

Wonder what kind of costume she got?

Halle Berry and fiance Olivier Martinez took her 4-year-old daughter Nahla for some Halloween shopping at Aahs in Brentwood on Friday.

The 46-year-old actress and fiance earlier spent the day at Variety’s 4th Annual Power of Women event in Beverly Hills. Glad to see that they made time for Nahla to pick out her Halloween costume!

Even power couples have to eat!

Last night, George Clooney and Stacy Keibler dined with Cindy Crawford and Rande Gerber at Spago in Beverly Hills and the foursome were certainly the best dressed in the building!

Clooney and Keibler are still going strong despite reports by The Sun claiming the contrary, as a rep for the couple denied any dissension between the two last month. They do make quite the pair!

On Friday, Rihanna took to her Twitter account to give fans a peek at a provocative promo for her new perfume.

"Here is my new add for a brand new fragrance #NUDE !!! Make sure you smell sexy, especially naked, this fall," the 24-year-old singer tweeted to her 26 million followers.

RiRi looked white hot in cream lace lingerie for the ad, which comes on the heels of her recent rendezvous with ex-beau Chris Brown in New York City. Brown recently broke things off with Karrueche Tran and some say it's because of the Diamonds singer. Guess they're going for a round 2!

Emma Stone looked very Boho-chic as she touched down at LAX last night after spending some time in Paris for Fashion Week and none other than her boyfriend Andrew Garfield waited patiently for her to return. How sweet!

The Amazing Spider-Man co-stars have been quite the couple since filming the blockbuster hit and while Andrew has been laying low, Emma keeps on trucking as she's set to star in the raunchy comedy Movie 43 with an all-star cast including Gerard Butler, Halle Berry, Hugh Jackman and Anna Faris. What a lineup!

Amber Heard and some friends decided to spend a day by the beach as the ladies visited an acupuncture clinic in Venice Beach on Friday.

The 26-year-old actress took a break from her stunning outfits as she wore some ripped jeans, cut-off sleeved shirt and some black boots.

The Rum Diaries star is set to appear next in Paranoia, a corporate thriller which will also star Liam Hemsworth, Gary Oldman and Harrison Ford. While she's been busy with that project, her rumored beau Johnny Depp is about to wrap The Lone Ranger. There's been no photographic evidence of her and the Pirates of the Caribbean star's secret romance, we're wondering are they still an item or not?

Loving the casual look!

Yesterday, Katie Holmes looked relaxed in a t-shirt, pin-striped pants and heels as she headed home after a workout at Soul Cycle in NYC.

The 33-year-old actress has handled single motherhood well and seems to make the most of her time when Suri's not around. It's been over two months since her ex-husband Tom Cruise has been seen with their daughter due to his hectic filming schedule, but there have been reports of Cruise looking for a place to call home in the Big Apple to be closer to his little girl. Love conquers all!
