Actress Jennifer Garner revealed that co-star Mark Ruffalo almost quit ‘13 Going on 30’ after rehearsing for the ‘Thriller’ scene in the film. The actress was the recipient of a star on the Hollywood Walk of Fame in Los Angeles. During the ceremony, his friend and former ‘The Adam Project’ co-star, 51, reminded those in attendance that the world was almost robbed of a pop culture moment 20 years ago.

While speaking at the event, she wondered if Reese Witherspoon, Jennifer Aniston, Gwyneth Paltrow and Keira Knightley agree with her that Ruffalo owes his "rom-com success to the scruffy hair, the untucked cute button down, both of which became like the norm for cute guys everywhere for the next 20 years."
