Socialite Tinsley Mortimer is single again after splitting from her businessman boyfriend.
The blonde beauty, who previously dated American Idol rocker-turned-Broadway star Constantine Maroulis, has been living with Brian Mazza since February (11), but he has now moved out and Mortimer is back on the single scene.
She tells New York Post gossip column Page Six, "He was a great friend and the relationship ran its course... I am dating and looking forward to some trips in Europe this summer."
