And it was all because of "Pregnancy-related sciatica," a condition that can occur during pregnancy involving severe back pain.
"Pregnancy related sciatica kicked in today but lucky I had Dr @lisa_wilkinson on hand for a deep tissue massage! Magic hands," wrote the radio host.
"I can't recommend @lisa_wilkinson highly enough for any lower back remedial pain you might have, magic elbows!!" Fifi captioned a video of the event.
Lisa also shared the video with her own fans, writing: "Beautiful @fifi_box is 28 weeks pregnant and and let's just say, she's having issues that only a buttock massage from a trusted girlfriend can solve!"
"So we did this before heading into @theprojecttv studio tonight. And yes, I'm available for hire!"
Earlier this year Fifi announced her pregnancy in a sweet video alongside her daughter, Trixie, five, revealing that she had conceived via IVF from an anonymous donor.
