Her long-term partner, Bobby Cannavale, did not be attending the ceremony with her.
Cannavale is instead going to a reptile convention in New Jersey to acquire a bearded dragon for their children.
During her acceptance speech, the 46-year-old Australian joked: “I want to thank my husband, Bobby Cannavale, who couldn't be here because we're getting a bearded dragon and he went to a reptile expo in New Jersey, so thank you, baby."
Byrne instead attended the Golden Globes with her brother, George.
