Radio host Amanda Keller is in hospital after suffering cardiac symptoms during the premiere of Unbroken.

The host of Sydney’s most popular breakfast radio program had been attending the premiere of Angelina Jolie’s new film with her co-host Brendan “Jonesy” Jones when she told him she was feeling unwell.

“We’re at the movie Unbroken last night, enjoying the movie,” Jonesy said on the pair’s WSFM radio show on Tuesday.

“Next thing she’s in the hospital getting tests, which is the wise thing to do.”
