Both stars are currently single after Cox ended her engagement to Snow Patrol's member Johnny McDaid in early December and Perry split from actress Lizzy Caplan in 2012.

Star magazine claims that Cox rushed into the arms of her former co-star following her breakup.

"It's no surprise that Matthew was one of the first people Courteney called when she ended the engagement," a source told the magazine, reports aceshowbiz.com.

"They've leaned on each other before, during her infertility struggle and his battle with addiction," the source added.

The insider claimed that the duo is planning to "take it slow" and don't wish to make their relationship public "anytime soon".

However, Gossip Cop has debunked the story. Citing its own source, the site says that the report is not true.

Earlier this year, the two were also rumoured to be dating after they were spotted together and kissing in public.
