Kathleen Robertson couldn't be happier about her Boss's big news.
Robertson, 38, who plays Kelsey Grammer's personal aide on the Starz show, gushed to PEOPLE at Sunday's Golden Globes about Grammer, who won best actor for his role in Boss, and wife Kayte Walsh expecting twins.
"They're lovely and wonderful and madly in love, and they're going to be amazing parents," Robertson said. "It's great news."
Meanwhile, Grammar, 56, and Walsh, 32, told PEOPLE that they haven't gotten into full prep mode yet.
"We're just taking each day as it comes," Walsh said. Added Grammar with a laugh: "We're waiting until it all hits. We know where to find diapers and stuff. It's easy to find cribs."
As for the gender of the babies – the couple said they're not revealing that just yet.
