The 32-year-old actor began dating the Sports Illustrated beauty in 2011, and they made their red carpet debut at the Cannes Film Festival in France last May.
However, their romance has ended and the couple has called it quits, reported Us magazine.
"It happened a while ago. It was a mutual call. They both needed their space. She has been very busy with her modelling work and travelling. He's got 'Star Trek' and his other projects keeping him busy," a source said.
Pine has previously been linked to actresses Beau Garrett and Olivia Munn and US reality star Audrina Patridge.
