The actor, 48, appeared onWatch What Happens Livewith Andy CohenThursday, where he dished to hostAndy Cohenabout his early behind-the-scenes romance with theCocaine Bearstar, 47.

“But it’s those sneaky PAs who get onto it, you know?” he added, noting that the crew members would be on their headsets talking about the pair.

“She gave it to me, but this is where it all falls apart,” Rhys teased. “I have no memory of this because I was very inebriated, but I left a very inebriated message on her answering machine, as people had in those days.”

“Which she didn’t find charming,” Cohen replied, to which Rhys said, “Not in the slightest!”

Detailing that Russell did not return his call, Rhys said, “It was a bit tragic,” and admitted that he has no memory of the actual kickball game at Grey’s house either. “It was a heady time for me back in those days,” he said.
