Zoe Saldana is not just expecting one baby -- she's expecting two!

The glowing actress stealthily revealed the exciting news to E! while at an event in L.A. When asked if she was dressing up for Halloween this year, the 'Guardians of the Galaxy' star reportedly rubbed her belly and replied:

"I might. I might need three costumes this year," she said. "I might have to make some adjustments, but it would be nice." So sweet!

We're not sure what it is about Halloween that makes celebs want to reveal baby news, but we kind of love it. Remember when Jessica Simpson confirmed her pregnancy with daughter Maxwell by dressing up as a "mummy"? So clever.

The twins will be the first children for Saldana and her husband Marco Perego, and it's clear that the two will be great parents.

"I love the anxiety, the pressure of the loud room full of yapping kids," Saldana has said (quote via E!). "But I'm a kid myself. I get along very well with animals and children. I dig them. I get them. They make perfect sense to me. A child speaks more sense than an adult half of the time."

Congratulations to the happy couple!
