Rose Byrne

AKM-GSI

She played a new parent in Neighbors—and now, Rose Byrne is expecting! 

The 36-year-old actress is pregnant, multiple sources confirm to E! News. This will be the first child for the Australian beauty and boyfriend Bobby Cannavale

Byrne was most recently spotted showing off her baby bump (and some leg!) while leaving LAX. The star's growing bun in the oven was on display in a loose-fitting flannel dress that included very high slits which flaunted her black-stocking-covered gams.

The Spy star and the American actor have been dating for about three years. In his 2013 Emmys' speech for his award for Outstanding Supporting Actor in a Drama Series for Boardwalk Empire, Cannavale called Byrne the "love of my life."

The good-looking duo made their red carpet debut as a couple at the CFDA Fashion Awards in June 2013. Around the same time, Byrne began to discuss her romantic life more publicly. 

"I was very shy and sensible as a child and pretty much into my 20s," she told the U.K.'s Stylist in 2013. "It was the same if boys liked me. I was very quiet and secretive about it and found romance icky. But as I've gotten older I've definitely tried to appreciate it more and delight in those sorts of things more because they are actually precious and special. I'm trying to soften a bit because I think I can be too...practical?"

She also opened up about life with her handsome man in the May 2014 issue of Elle Canada. 

"I'm not a good cook, but seeing someone enjoy what you've made is so satisfying," she said, describing a perfect Saturday evening with her beau, adding that she's "trying to get better at romance."

"To be honest, I'm not naturally that much of a romantic person—Australians don't like making a fuss," the actress admitted. "I have trouble with things that feel very manufactured, like Valentine's Day." 

The couple have co-starred together in two films, including 2015's Spy and 2014's Annie

Prior to Cannavale, Byrne dated fellow Aussie actor Brendan Cowell for six years. 

Congrats to the happy couple. Can't wait to meet the little one!
