TomKat! Courteney & David! Arnold & Maria! How Celeb Couples Spent Memorial Day Weekend

On Memorial Day weekend, celebs are just like us! They hit the beach and BBQs like any average American, but the company at their holiday bashes tends to be of the boldface variety. 

Producer Joel Moore's annual Malibu fete brought out the big names, including Tom Cruise and Katie Holmes with Suri in tow. But while one on-again, off-again couple put on a united front for the party, another opted to celebrate separately...

Courteney Cox and David Arquette made it a family affair, bringing daughter Coco along to the star-studded soiree, where Robert Downey Jr., Barbra Streisand, January Jones and Guy Ritchie were all in attendance.

Freshly split duo Arnold Schwarzenegger and Maria Shriver did their own things this weekend.

The Governator was snapped taking his motorcycle for a solo spin in Malibu while Maria was all smiles during dinner with friends and some of her children Sunday night in the same town.

On another coast, our own Chelsea Handler celebrated her Hamptons magazine cover with beau Andre Balazs.

The hotelier escorted Chelsea to the party at the Southampton Social Club, but the couple seem to be staying undercover...for now. Although they arrived in the same SUV along with some of Chelsea's family members, they didn't pose for photos together.

Real Housewife Ramona Singer was enjoying the same party (and her cocktails, natch) with hubby Mario, while Kelly Bensimon came solo.
