And by stars, we mean dad Mick Jagger – who attended the ceremony dressed in Jagger-esque green suit, purple scarf and print shirt – and mom Jerry Hall, wearing a flower print dress and white coat.
James – who stars in HBO's Vinyl, which is produced by his dad Mick and director Martin Scorsese – opted for a no less colorful blue suit, with coordinating print, while Sharma wore a white lace wedding dress.
Hall is a newlywed herself, after a March wedding to media mogul Rupert Murdoch, who attended the wedding with her.
(Hall and Mick were together for more than 20 years and have four children together; they split in 1999.)

James and Sharma's wedding celebration this weekend comes seven months after the couple wed in September, at a low-key hilltop ceremony in the Catskills, in upstate New York.
It appears that neither parent attended those nuptials, but both were by their son's side on Saturday.
