Cera is a delight as Ken's friend, based on a doll that Mattel introduced in 1964.

The “Barbie” star said he felt "paranoid" over his rising fame after the films soared at the box office.

"I don't think it took much convincing to get her to do it," Cera said of the Fenty founder's slap in the 2013 comedy "This Is the End."

The "Scott Pilgrim vs. the World" co-stars were closer than the public realized at the time.
