Smiling Jimmy Barnes photographed outside days after heart surgery

A smiling Jimmy Barnes has been snapped tucking into a Sunday lunch just days after he received open heart surgery.

Barnes underwent the major surgery to fight a bacterial infection last week.

His wife Jane, who has been sharing updates on social media for concerned fans, posted an update on his Instagram account overnight, sharing of a picture of the beloved rocker eating a roast dinner with his family.

"Here's Jimmy's first Sunday roast," she posted.

"We are getting fresh Darlinghurst air. We're a lucky family. Happy Sunday all you good people."

Last week Barnes was photographed walking around the hospital and sitting up out of bed.

"Day three post op and we had a few walks up and down the hallway," Jane said in an update on X yesterday.

"A tough and fragile day but here's a big, brave smile for us. Keep up the good work, Jimmy."

The Cold Chisel frontman, 67, was hospitalised at the end of last month with pneumonia.

He revealed last week that he needed to undergo open heart surgery to replace the infected valve.

Barnes is expected to take at least the next four months off, having cancelled his performance at the Rock the Boat 2023 cruise festival.
