The couple announced divorce plans in March (12) after 11 years of marriage, and Garth revealed in a recent interview with a U.S. magazine that she turned to her pal Perry in her time of need.
Rumours suggested the relationship had moved on from being purely platonic, but a spokesperson for the actor insists the speculation is wrong.
The rep tells E! News, "This story is not true."
Garth has been linked to photographer Noah Abrams after they were spotted holding hands on a day out in Los Angeles earlier this month (Aug12).
