The annual event benefits the Australian charity effort working to support children with a life-threatening disease.

“She just 100 percent outed your engagement,” Brenneman said to Nixon.

“I did,” Walsh admitted. “I just outed our engagement.”

Her beau seemed perfectly happy with the accidental announcement, smiling on camera and chatting happily to Brenneman.

The pair reportedly met on a cruise and Walsh ended up living with Nixon in Australia throughout much of the pandemic. “I didn’t really want to go back to New York in the middle of a pandemic when it was pretty gnarly, to say the least,” she told theDaily Telegraph. The actress reportedly opted tostay in Australiafor several months instead of returning to the U.S.
