Selena Gomez Dumps Justin Bieber (VIDEO, PICTURES)

One of the biggest star couples in the world are said to have parted ways, as Selena Gomez has apparently called it a day with Justin Bieber.

The Disney actress has apparently ended their relationship as she has reportedly had some trust issues with her boyfriend of two years.

A source close to Selena told The Sun: "She broke up with him a week ago. They were apart so much that it got complicated. She had some trust issues. It's not easy but the relationship needed to end."

Selena's concerns may have already been confirmed as Justin has been seen out with Victoria's Secret model Barbara Palvin. Justin reportedly took the Hungarian model out for a romantic evening to see The Lion King on Broadway.

Their date came a day after Justin performed at the famous Victoria's Secret show, which saw Barbara take to the catwalk wearing nothing but sexy underwear.

Palvin is one of the rising stars of the fashion world, and has also modelled for designers including Louis Vuitton and Vivienne Westwood.

Justin and Selena made up one of the hottest young couples in Hollywood, with the Canadian star selling millions of records worldwide and taking his first steps into the world of acting with an appearance on CSI: Crime Scene Investigation.

Selena is also carving out a stellar singing career for herself, while her new movie Spring Breakers is set for release next year. She also recently scooped the US Glamour Woman of the Year award, despite being only 20 years old.
