People were quick to point out that the name of the single was "appropriate" and "autobiographical" in the wake of ex-girlfriend's Britney Spears' claims about their relationship.
Britney revealed last year that she fell pregnant when she was dating Justin between 1999 and 2002.
"It was a surprise, but for me, it wasn't a tragedy," she wrote in her memoir The Woman In Me. "I loved Justin so much. I always expected us to have a family together one day. This would just be much earlier than I'd anticipated. But Justin definitely wasn't happy about the pregnancy. He said we weren't ready to have a baby in our lives, that we were way too young."
She went on talk about having a termination: "If it had been left up to me alone, I never would have done it. And yet Justin was so sure that he didn't want to be a father. To this day, it's one of the most agonising things I have ever experienced in my life."
After Justin announced the new single, comments quickly piled up on his social media pages:
"An autobiographical song based on the title,' one person wrote.
"Given his past I'd say this is appropriately titled." agreed another.
Britney also has a song called Selfish that was a bonus track on her Femme Fatale album in 2011. (Music-News)
