Petra Nemcova: Supermodel Dishes on Super Wedding Plans

Beauty gives us the scoop on dress and location, calls fiancé a "real man"

Petra Nemcova has begun planning the wedding she's always dreamed about.

The tsunami-surviving beauty, who is newly engaged to British actor Jamie Belman, exclusively tells E! News she knew "within days that he was the one."

"We both knew right away, both of us," Nemcova told us today at the Luca Luca show at Lincoln Center in New York.

And she also spilled some good wedding details, including the designer behind her one-of-a-kind gown...

First, Nemcova and her love will spend Valentine's Day in New York together, then head back to England to scout out locations for the big day.

"I'm with him every single day," she said. The couple have been together for nine months now.

As for the wedding, they are planning to invite 130 guests.

"It will be both a mix of formal and fun and craziness," she said. "I want everyone to feel comfortable and appreciated."

Nemcova's already chosen her dress, a Marchesa designed just for her, and the couple will exchange vows somewhere in the U.K.

"We are looking at locations now, trying to see what's best," said the Czech-born babe, who was previously linked to Sean Penn before meeting Belman. 

As for her beau, she said she knew she wanted to marry him immediately—and even placed meeting him as her luckiest moment, even above surviving the 2004 asian tsunami, which claimed the life of then-boyfriend British photographer Simon Atlee.

"First was meeting my  fiancé," she said. "Then surviving the tsunami. He's a real man, there are no layers of phony. he is who he is he's incredibly loving and he's just really what I look for. I knew right away about him, really really fast."

Nemcova, best known for her Sports Illustrated swimsuit posing, was happy to be siting front row at the show today, saying she appreciated not having to walk the runway and deal with the stress that comes with it.

"It's nice to be sitting and watching the incredible creations without being on the catwalk and having the hard work," she said.

When we asked if she was ready to have some babies right away, the model said sometime in the future.

"Not yet, I am enjoying this, the moment for now," she said.
