Maria Shriver, Cheryl Hines and more stepped out over the weekend to help raise money for Best Buddies International.
The non-profit organization, founded by Maria's brother Anthony K. Shriver in 1989, works to put individuals with intellectual disabilities into the workplace.
Stars helped raise $4.5 million for the charity at the 10th Anniversary Best Buddies Challenge where 1,500 people rode 100 miles down the Pacific Coast Highway.
"Two people come together and hang out and really form a friendship that's very special, said Cheryl Hines. "It gets better and better every year."
