She's been keeping a low profile following her reported New Year's 'hook up' with cricket star Michael Clarke.
But eyebrow stylist Kristin Fisher, 36, made a low-key appearance on Wednesday as she stepped out to run errands and visit the gym in Sydney.
Kristin, whose 'rendezvous' with Michael, 40, reportedly left his ex Pip Edwards, 41, 'unhappy', showcased her etched abdominals in a black crop top and leggings.

The mother-of-two looked fit as a fiddle as she arrived at celebrity trainer Jono Castano's Acero gym in Kensington.
She went makeup-free and completed her look with a white-and-green striped shirt, which she removed and tied around her waist after arriving at the gym.
Elsewhere on Wednesday, the brunette was spotted dropping her young children Eddie and Lila off at their father Chris Barnes' home.

Kristin announced her separation from Chris in early 2020, revealing that their split would remain amicable for the sake of their two children.
Kristin's outing comes days after reports surfaced claiming she'd 'hooked up' with Michael Clarke, at a New Year's Eve party hosted by Dina Broadhurst and her partner Max Shepherd in Vaucluse.
According to The Daily Telegraph's Confidential, Pip - who split with Michael in early December - 'isn't happy' about the reported hook-up.
