Singer Justin Bieber and his actress girlfriend Selena Gomez made a perfect couple, but they have reportedly parted ways.

The news comes after Bieber, 18, was seen chatting up models backstage at the Victoria’s Secret show on Wednesday, and this could have been the reason behind the split, reports eonline.com.

According to a source, the duo broke up about a week ago. They were last spotted together on October 20, and packed schedules also perhaps took a toll.

“Because of their crazy schedules, it was getting harder and harder to maintain a relationship,” said the source.

The couple started dating 18 months ago.
