Britney Spears revealed that her friend Zoe Saldana is pregnant with twins. It's great news but Saldana, who has been mum about her pregnancy, has yet to confirm previous rumors that said she and husband Marco Perego were expecting twins.  

Spears sat down with "Entertainment Tonight" and was asked if she and Saldana would ever film another movie together. The two costarred in the 2002 film "Crossroads."

"Who knows? That's a very good idea. But she's pregnant with twins right now," Spears said unaware she just dropped major baby news. "So I'm sure she's got a huge future ahead of her."

It wasn't until last month that Saldana confirmed her pregnancy while accepting an Ice Bucket Challenge. In a video the "Guardians of the Galaxy" actress posted on YouTube she explained that she couldn't fully participate because of her growing baby bump.

"I am accepting James Gunn's challenge to take on the ice bucket challenge in support of finding a cure for ALS. Obviously, I can't do it myself," Saldana said rubbing her belly.

Instead, her husband volunteered to complete the challenge. Spears, who is a mother of two, told "Entertainment Tonight" that she offered Saldana some advice joking telling the actress that she's "not ready."

"You don't know what you're in for," Spears laughed.

When news of Saldana's pregnancy first surfaced online she was angry and tweeted a quote from Polish president Lech Walesa, "I believe that any violation of privacy is nothing good."

"I would like to thank all the [expletive] media for invading our privacy," the 36-year-old added.

A source told US Weekly that the actress "will only announce the news [of her pregnancy] when she's ready," but added that Saldana and Perego are "thrilled."
