The 20-year-old actress-turned-singer allegedly dumped the `Baby` hitmaker last week almost two years after going public with their relationship in February 2011 because she couldn`t trust him when they weren`t together.

A source told People magazine: "She broke up with him about a week ago.

"With them being apart so much it got complicated. She had some trust issues. It`s not easy, but the relationship needed to end."

News of the couple`s split broke on 09.11.12 just hours after Selena posted a picture on twitter of a photograph of Justin with Hungarian Victoria`s Secret model Barbara Palvin in the background.

The Canadian popstar, 18, was spotted on a date with the 19-year-old model in New York earlier this week.
The pair - who met when Justin performed at the Victoria`s Secret show in the city - enjoyed a trip to see the Lion King on Broadway.

The break-up is surprising as Justin recently revealed he was proud to have Selena by his side.

He said: "I never make [Selena] separate from me because I don`t want her to ever feel like I`m ashamed of her. Because I feel like a lot of guys do that, especially in the business. They don`t want to be seen with the girl, so they`ll make them ride in separate cars. They`ll do that `get away` stuff. [Selena and I] get away together."
