"She is staying strong. It's a very difficult time for her. A public divorce on a reality show – it was impossible for me, so I empathize with her," Grammer, 44, told PEOPLE Monday at TV Guide's annual Hot List Party in West Hollywood.
Maloof, 51, and Dr. Paul Nassif just reached a divorce settlement. And Grammer says she has been in touch with her Real Housewives of Beverly Hills costar to talk girlfriend to girlfriend.
"She'll get by. It just takes a while," says Grammer.
What's the secret to getting through it? New love – and lots of sex, she says.
"A man helps, you know," she says. "Sexual healing helps."
The more of it, the better, in fact. "At our age, I can't believe it," says Grammer, whose romance with Dimitri Charalambopoulos will be featured on the Bravo show. "It's like three times a day, and I am like, 'Oh my God.' It's a great workout. The first year it was three times a day. It was insane."
She adds: "Who doesn't love a great partner in bed? I mean, come on. Especially after a bad divorce."
