Inching closer to going down the aisle, Beth Ostrosky tells PEOPLE that she and Howard Stern will marry "probably definitely" next summer in the Hamptons.
She also thinks he's going to be "Groomzilla."
"We're getting ready for my wedding, we're setting a date. It's coming true," the model said recently at the Cinema Society and W
magazine screening of Elizabeth: The Golden Age
at Manhattan's Tribeca Grand Hotel.
As for an actual wedding date, Ostrosky – who became engaged to Stern
on Valentine's Day this year – told PEOPLE that's she's pinned the shock jock down to "the vicinity of next summer.
"I'm probably definitely going to do it in the Hamptons," she said. "There are so many designers names swirling around in my head – it's so exciting."
When the wedding takes place, it will mark a first marriage for Ostrosky, 35, and the second for Stern, 53, who split from first wife Alison in 2000.
This summer, Stern – expressing the virtues of a long engagement
, as well as his dream of getting married barefoot on the beach near the couple's home in Southampton – told PEOPLE, "We think for another year we could be engaged."
Asked on Wednesday if Stern (who wasn't present at the movie premiere) had particularly strong opinions on prospective details of the upcoming event, Ostrosky said, "He cares about everything, which is so cute. I think he's going to be the Groomzilla."
She added, "He definitely has opinions, but it's about me, what I want. He's been great so far. He's been so supportive, that's why we work."
