US pop star Katy Perry gave Tony Abbott a lecture on gay marriage the last time she was in Australia but couldn't remember the PM's name when asked during her latest visit.
The singer is in Sydney to promote her upcoming world tour and was quizzed about her knowledge of Australia.
When asked by Seven Sunrise host Samantha Armytage on Wednesday if she knew the name of Australia's Prime Minister she said: "This guy I was on the phone with that I don't agree with, but I like him a lot ... Tony?" she replied.
She didn't do much better on Australian fauna, saying she thought wombats were fictional.
Before the live interview, hundreds of screaming fans lined up to see the 29-year-old outside the network's studios in Martin Place.
Perry took selfies and signed autographs on the red carpet, greeting fans ranging from the preschoolers to grandmothers.
"Where's my coffee?" the pop star joked as she sat down for her interview.
She was soon back on her feet when her hosts surprised her with an Australian petting zoo featuring a baby saltwater crocodile, a koala, wombat, and a diamond python.
"I never thought I'd see a wombat in person because I thought it was a fictional animal," she said.
"But Australia has all kinds of animals. Do you have a pegasus?"
Perry last week announced her Prismatic World Tour is coming to Australia in November, but has not confirmed who will be touring with her.
Preparations for her arena shows are already underway, she said.
"I'm really focused right now, I've cut out all alcohol.
"I'm almost 30 guys, my body doesn't snap back anymore. I can't just go around eating McDonalds like I used to."
