To mark the occasion at Garner and husband Ben Affleck's home, Reese Witherspoon brought her steady companion since February, Hollywood agent Jim Toth, and her children, Ava and Deacon.
Also singing "Happy Birthday" to Garner: Molly Sims, Jason Bateman with wife Amanda Anka, Tobey Maguire with Jen Meyer, Don Cheadle, Jimmy Kimmel, Jon Favreau and Laurence Fishburne.
The weekend of celebrating actually started on Friday, when Garner and older daughter Violet, 4, devoted part of the afternoon to pampering mother-daughter pedicures at Lemon Nails & Spa in Pacific Palisades.
