Petra Nemcova, 27 and James Blunt, 32 are over, People has confirmed.
A source close to Blunt told People, "They split in February. It's very amicable, they remain good friends."
The pair were last seen together over Oscar week in February, when they went to many parties.
But in recent weeks, Blunt has been visiting the Hollywood nightlife solo. He was spotted on the same night – March 21 – at both Les Deux, where he hung with pal Robbie Williams, and later at Teddy's, where he partied with Lindsay Lohan, Kelly Osbourne and Amy Winehouse.
According to a clubgoer at Teddy's, "Lindsay [Lohan] and James were never affectionate, but they did seem flirty, standing right next to each other, and constantly talking."
Nemcova and Blunt met in December 2005 and started dating the following year. In November 2006, rumors circulated that they'd split, but the couple denied the stories.
"We never got separated," Nemcova told People at the time. "There was some stuff going on in the press, but it didn't come from a right source – obviously. We're very much in love."
Blunt was the Czech model's first serious relationship since her longtime beau, photographer Simon Atlee, died in Thailand in the 2004 tsunami. Nemcova survived by clinging to a palm tree for eight hours, and suffered a broken pelvis.
