WATCH: Barty and Stosur play "This or That"

The Australian Fed Cup team is getting set to host France in Perth this weekend for the 2019 final, and the Aussies are mixing in some fun between practices and media obligations.

Ashleigh Barty and Samantha Stosur played "This or That" with Barty revealing she has no interest in either Taylor Swift or Kanye West. Though all of the questions were silly, the silliest may have been "Vegemite or peanut butter."

"I travel with my own Vegemite," Barty said.

The world No. 1 does more than that. Her name become part of the Vegemite brand with Bartymite taking over store shelves.

Barty's teammate Ajla Tomljanovic and Fed Cup captain Alicia Molik also played the same game.

Tomljanovic is making her Fed Cup debut for the green and gold this weekend, after switching nationalities from Croatia to Australia. She's been a resident of Australia since 2014.

"This year I told myself, ‘I’m not going to think about it’, just because I don’t want to get my hopes up and then get crushed," Tomljanovic told Tennis Australia. "So I’m just really excited that I finally have the opportunity."

She'll be boosted by teammates Barty, Stosur, Priscilla Hon and Astra Sharma. Team chemistry seems to be doing just fine, across multiple sports.

Australia is seeking its first Fed Cup title in 45 years. Action begins on Saturday.
