The teen pop idol and his singer-actress girlfriend are claimed by E! News to have decided to call time on their relationship due to the pressures of work.
A source apparently told the site: "Because of their crazy schedules, it was getting harder and harder to maintain a relationship."
The claim comes just over a week after Biebs posted a picture on his Instagram account which showed him looking solemn and was accompanied with an anagram of the word "single".
And the 18-year-old has this week been photographed with stunning Hungarian model Barbara Palvin after mingling at a Victoria's Secret catwalk show.
