It comes as no surprise, perhaps, that an Academy Award winner and top Hollywood agent would have a star-studded social circle, but like any other guest list there’s a story behind how the folks who attended the nuptials landed an invite.
Robert Downey Jr. and his wife Susan
The Iron Man star relies on a super agent to help navigate his career: Toth himself! While the groom is pals with the Downey Jr., Witherspoon also has a friendship with the actor and even had him and his wife up to her Ojai, Calif., estate in 2008 where they went hiking.
Scarlett Johansson and Sean Penn
Johansson is linked to the newlyweds through the groom: Toth is her agent at Creative Arts Agency. And the actress upped the star power at the wedding when she brought her new beau, Sean Penn, to the nuptials on Saturday.
Alyssa Milano and hubby David Bugliari
Toth and Bugliari are work associates: They’re both high-powered agents at CAA. But their brides have a connection, too. Witherspoon and Milano appeared together in the 1996 thriller Fear with Mark Wahlberg.
Matthew McConaughey and Tobey Maguire
Okay, these two Hollywood hunks didn’t come to the wedding together, but both attended because of their connection to the groom. McConaughey and Maguire are among Toth’s A-list clients.
The newly single star is a pal of both the bride and the groom, and the trio share friends in common.
