The romance between American pop singer Britney Spears and L.A. Models model Isaac Cohen is over.

Cohen decided to end the relationship, his agent, Brandi Lord of L.A. Models, told People magazine.

Lord called the split between the two 25-year-olds "very amicable."

Spears, who was visiting New York after the breakup, was first spotted with Cohen Jan. 2, boating off the Marina del Rey, Calif., coast.

When the two first started dating, Cohen was compared to Spears' ex-husband, Kevin Federline, because of his scruffy look.
