Britney Spears shared the news Zoe Saldana is expecting a double arrival
Asked whether she and her Crossroads co-star Zoe would do another film together, Britney replied, "Who knows? That’s a very good idea. But she’s pregnant with twins right now. So I’m sure she’s got a huge future ahead of her."
Avatar star Zoe, 36, has been considerably less vocal about her pregnancy.
She sparked reports that she was expecting his first child with husband Marco Perego at the premiere of Guardians of the Galaxy, where she showed off her little baby bump, and the following day her spokesperson confirmed the news.

It was then reported that the actress could be welcoming two children when she gives birth, thought to be around January. But until now, there has been no confirmation.
Zoe is notoriously private when it comes to her personal life. She married Italian artist Marco in secret in June, but didn’t confirm her new marital status until six months later, during a December appearance on Jimmy Kimmel Live.

Until then there had only been speculation that Zoe, who previously dated Bradley Cooper, had married Marco. "It was super small but very romantic and beautiful," a source told Us Weekly in September, adding that the couple had "known each other for a long time" and had "great chemistry".
