Rose Byrne believes motherhood is huge responsibility
The 37-year-old star said her son has brought out better qualities in her but still he is a big responsibility, reported Hello! magazine.
"You have this huge responsibility you didn't have before because there's someone you have to keep alive," Byrne said.
The "Spy" star revealed their friends are tired of her and her actor husband Bobby Cannavale talking about Rocco all the time.
"I'm pretty sure everyone who knows us is sick of it," she said.
