Bumpin' Byrne!

Rose Byrne is keeping busy during her first pregnancy. The actress was spotted filming her upcoming movie Neighbors 2: Sorority Rising with costars Seth Rogen and Zac Efron in L.A. on Monday, Oct. 26.

The Australia native, 36, showed off her growing baby bump in two wardrobe changes. In one photo, she enhanced her curves in eye-catching red pants and a white T-shirt. In a second, she covered up in an oversized peacoat. It's unknown whether her character, Kelly Radner, is pregnant in the sequel. (Kelly and Rogen's character, Mac Radner, already have a child in the movie.)

Us Weekly confirmed earlier this month that Byrne and her longtime boyfriend, actor Bobby Cannavale, are expecting their first child together. Byrne stepped out with a noticeable baby bump at LAX on Oct. 22.

The soon-to-be parents began dating in 2012 and made their red carpet debut at the CFDA Fashion Awards in NYC in June 2013.

Neighbors 2: Sorority Rising hits theaters on May 20, 2016.
