Zoe Saldana is on a promotional tour for her new movie Guardians of the Galaxy, and after giving us a peek at her baby bump in a tight skirt over the weekend, she kept her tummy covered up while stopping by Jimmy Kimmel Live on Monday.

While she hasn't exactly confirmed that she and husband Marco Perego are expecting their first child together, rumors have been swirling for the past month that the 36-year-old starlet has a bun in the oven.

While she hasn't been chatty about that during interviews, she did share a funny tidbit with E! News the other day when asked about all the green body makeup she had to wear to play the comic book character Gamora.

"They would have a bath just ready for me," the actress joked. "I would just submerge myself in a very hot bath and that tub was just absolutely green. We had a very good makeup removal process that lasted about an hour and 15 minutes. We would take a lot off. I just hated going to bed with all those chemicals still on me even though I rubbed them off." That doesn't sound very fun!
