Kris Jenner isn't the only celebrity mom who whooped it up with a big 60th birthday bash this weekend.

But while Kris partied at a $2 million Great Gatsby-themed soiree at The Lot in Los Angeles on Friday night, journalist Maria Shriver enjoyed a more low-key -- yet still A-list party -- a few miles away at the Montage hotel in Beverly Hills, California, on Nov. 6.

Friends including Oprah Winfrey, Tom Hanks, Rob Lowe, Sean Hayes and Stevie Wonder enjoyed treats including cupcakes featuring vintage photos of Maria, reports ETonline.

Stevie also joined the house band on stage to sing to the birthday girl, who can be seen dancing with pal Sean to Stevie's "Signed, Sealed, Delivered I'm Yours" at one point in the night as seen in a video posted on TMZ. "Stevie KILLING it," Rob Lower captioned another video he shared of the music legend in action.

Stevie also serenaded the Kennedy family scion with another classic: "Stevie Wonder singing "Happy Birthday to you!" to my dear @mariashriver," Oprah Winfrey captioned an Instagram photo of Maria enjoying her bash. "A phenomenal woman and friend since our 20's."

Three of Maria's four children were also there to fete their mom, reports ETonline: Christopher Schwarzenegger, Katherine Schwarzenegger and Patrick Schwarzenegger. The latter two shared playful snapshots from the photobooth inside the party on their social media accounts.
