0411_petra_singlePetra Nemcova just can't catch a break in love -- the model just called off her engagement.

A rep for the 32-year-old confirmed the sad news to People, saying, "Petra Nemcova and Jamie Belman confirm their separation. They remain close friends and thank their families for their continued support during this time. There will be no further comment on the matter."

Petra, who appeared on season 12 of "Dancing With the Stars" last year, had been engaged to British actor Jamie, 28, since December of 2010.

This was the second engagement for Czech native.

Petra and then-fiancé Simon Atlee were vacationing in Thailand in December of 2004, when the 9.2 Indian Ocean Earthquake struck.

Sadly, Simon was swept out to sea in the ensuing tsunami. Petra sustained a broken pelvis and various internal injuries, escaping a similar fate by holding onto the top of a palm tree until she was rescued eight hours later.

Petra dated British singer James Blunt after her tragic loss, though that couple split after just a year together.
