"She was very pleasant," Walsh, 29, told PEOPLE following a Cinema Society screening of No Strings Attached. "It was all very pleasant … Everything is good."
At the DKNY Jeans-sponsored bash at New York's Soho Grand with his fiancée, Kelsey Grammer played coy about their upcoming nuptials, but did tell PEOPLE, "Whatever plans are being made are being made quietly."
But the cat will be out of the bag soon, he said.
"People will know in time," Grammer, 55, said. "We'll make a little announcement in a few weeks."
How is Grammer feeling these days? "I've never been happier in my life," he says.
Added Walsh: "[I'm] extremely happy."
