"I am accepting James Gunn's challenge to take on the ice bucket challenge,” the "Avatar" actress, 36, tells the camera after the director nominated her. "Obviously, I can't do it myself so I nominate my husband to take on the challenge," she added, while turning to the side to show off her growing baby bump.
Willingly taking on the challenge instead is her hubby Marco Perego. Rocking a man bun and sweatpants, the handsome Italian artist, 35, gets drenched by the ice water and jumps into a nearby pool; the couple nominates James Cameron, Aileen Getty, Ron Burkle, and Salma Hayek to take on the challenge next.
Last month, Us Weekly broke news that the "Guardians of the Galaxy" actress was expecting her first child. The private star has been hesitant to publicly announce she's pregnant; at the time, a source told Us: "She will only announce the news when she's ready."
Saldana, who secretly married Perego last September, "has always wanted a big family," another source told Us.
