Eva Herzigova says she's looking forward to motherhood – and reveals to PEOPLE the sex of her baby.
"We are having a boy!" the supermodel-actress, 34, said at a Chopard dinner at the Cannes Film Festival on Wednesday evening. "I am so excited. I cannot wait for motherhood."
With Italian boyfriend Gregorio Marsiaj at her side, the Czech-born Herzigova says that although they have thought of some names for their first-born, they want to wait until the big day to make the final decision.
"We haven't chosen one name but we have a little list of names we like," she says. "I think you have to wait until that moment and see what names suits. I don't think you can say before hand."
Herzigova – who recently told the UK's Sunday Times
she has no intention
of following a strict, post-pregnancy diet – walked the red carpet for the premiere of the Jude Law-Norah Jones movie My Blueberry Nights
in her bespoke, sunset orange full length Valentino gown, before attending the Chopard dinner at the exclusive Nikki Beach.
"I was nervous on the red carpet because I am obviously pregnant," she said, "and I only have two more weeks to go!"
Dad-to-be Marsiaj had just one thing on his mind. "I wanted to be here for Eva and for our child," he said, placing a hand on his girlfriend's round stomach. "I am here to support her."
