Jennifer Lopez and Casper Smart split

Jennifer Lopez has split from her boyfriend of two-and-a-half years Casper Smart, according to a report.

Us Weekly magazine is reporting that the I Luh Ya Papi singer has reportedly called time on her two-and-a-half year relationship with the dancer-and-choreographer with the amount of time the pair were spending apart being the main reason for the break-up.

A source told Us Weekly magazine: "It has actually been an amicable process that started a few months ago. It wasn't an easy decision, but they decided to stay friends ... Their relationship couldn't work with the distance. He started trying to establish his own life and career, and she is so focused on hers, and they just couldn't be all about each other any more."

Lopez, 44, has been coping fine since ending the romance with Smart, 27, and is completely focused on promoting her upcoming album 'A.K.A.' and her live shows, which kicked-off with a free concert at Orchard Beach in The Bronx, New York, this week as part of a national music series.

The source added: "She's so focused on promoting the album. They are both in a good place now."

In recent weeks, Smart has been accused of cheating on Lopez with transsexual bikini model Sofie Vissa, whom he met and exchanged sexual messages with online first.

However, Smart has denied the allegations - and subsequent claims involving a second transgender model - and Lopez reportedly believes him.

The insider said: "The scandal had nothing to do with it. He insists none of that is true and she believes him."

The former couple were first linked together in November 2011 just a few months after the singer-and-actress split from her ex-husband Marc Anthony - with whom raises six-year-old twins Max and Emme.
