To top off her memorable summer, Saldana's film Guardians of the Galaxy broke box office records earlier this month. The fantasy flick landed at No. 1 and earned an estimated $94 million in its opening weekend. Though she hasn't publicly announced her pregnancy, Saldana proudly showed off her growing baby bump on several red carpets while promoting the blockbuster smash.
