Petra Nemcova and her fiance of over a year, Jamie Belman, won't be heading down the aisle, after all.

A rep for the model, 32, confirmed to Us Weekly that the pair have called off their wedding.

"Petra Nemcova and Jamie Belman confirm their separation," Nemcova's rep tells Us. "They remain close friends and thank their families for their continued support during this time. There will be no further comment on the matter."

Nemcova and British actor Belman, 26, first hooked up in spring of 2010; Belman popped the question to the swimsuit model eight months later.

This was Nemcova's second engagement--in 2004, her fiance at the time, Simon Atlee, was killed in the tsunami that hit South Asia, where the pair was vacationing.
