Justin Bieber and girlfriend Selena Gomez have allegedly broken up on numerous occasions, with sources claiming their relationship is not as "solid" as we may think.
According to TMZ, the cute couple - who have been together for around 18 months - split last week, only to kiss and make up soon after.
A separate source 'close' to JB and Gomez has since told The Mirror that their romance is quite volatile at the moment, revealing: "They might be young, but Justin and Selena's is a very adult relationship.
"They have had to grow up really fast because of the pressures of their careers.To begin with, their similar situations complemented each other, but now they seem to be drifting apart."
Both Justin and Selena are yet to comment on the split rumours, with the Biebster recently revealing that he is yet to have his heart broken by a girl.
In other Justin Bieber news, The Sun has claimed that a song from his debut album My World - entitled Bigger - could be about the breakdown of a sex-sex relationship after writer Frank Ocean admitted to being in love with a man earlier this week.
