Justin Bieber's 2015: Year starts single
It's safe to say Justin Bieber had the biggest year of his life in 2015 even if it did have as many ups and downs as a rollercoaster.
The pop megastar began the year newly single and with a fresh start after his long-term on/off girlfriend Selena Gomez abruptly broke off their romance.
The 22-year-old stunner felt "completely humiliated" that her boyfriend was meeting up with model Kendall Jenner behind her back and wrote on Twitter at the time "learning lessons the hard way". Despite friends of the couple insisting Justin would win her back - and numerous attempts throughout 2015 to spark the romance - it never happened.
