Los Angeles: Singer Justin Bieber`s childish and attention-seeking behaviour reportedly forced Selena Gomez to end their relationship, says a friend of the singer-actress.
The duo was together for over two years before their relationship hit a rocky end during New Year.
"Justin is super needy and can be a big baby around Selena. It is hard for him to make real friends because he likes the temporary attention of strangers, but didn`t realise how it hurt Selena," radaronline.com quoted a friend as saying.
Bieber`s closeness with other girls had also started to bother Gomez.
"Selena didn`t feel Justin was respectful of their relationship. She was constantly catching him in positions with other girls that would make her uncomfortable. She would get super jealous," the friend said.
