's taste buds will be in for a treat when she ties the knot with John Legend
"He's such a romantic. He's so sweet," Teigen told PEOPLE about her husband-to-be at Surrender Nightclub's Summer of Swim party in Las Vegas on Friday. Even sweeter? What Teigen's plan for dessert.
"Food is really important to me," said the model and Model Employee
host. "I'm not a big sweets person, which is why I'm really specific about the cake, which is going to be a really multi-layer cake. It's layers and layers of crepe and pastry creme in between with raspberry sauce."
On the big day, 27-year-old stunner will wear a Vera Wang dress and Legend will sing to her. But the cake, she said, is "the only thing I'm really specific about."
Delicious desserts aside, Teigen recently said
she is also thrilled to be celebrating with friends.
"I'm excited. I can't wait for the ceremony. [John] and I have been working and traveling so much that we just let our wedding planner do everything. We're not neurotic about it. I just want to finally see all of my friends in one area."
