Pop star Justin Bieber gushed about his love for his on/off girlfriend Selena Gomez just days before their reported split in a new Tv interview.

Gomez allegedly ended the pair's almost two-year romance at the end of October (12) - due to their hectic work schedules.

And now it's clear the reported break-up took Bieber by surprise - because he spent much of his hour-long talk with Oprah Winfrey for a new Tv expose discussing his leading lady.

During a sit-down chat taped one week before Halloween (31Oct12), Bieber said, "I am a lot about really genuine people and I feel like she is one of the most genuine people and she just has a good heart. I can talk to her about anything."

The 18 year old also opened up about how he and Gomez manage to avoid the paparazzi on date nights, as well as how he hoped his love-struck fans will take it easy on Gomez and stop sending her nasty Twitter.com messages.

He added, "At the end of the day I still have to be happy. I can't be single my whole life."

The Tv conversation aired on Oprah's Next Chapter on Sunday (25Nov12).

It is unclear what the status of Bieber and Gomez's romance is - they sparked speculation of a romantic reconciliation last week after they were snapped holding hands at an American Music Awards afterparty on 18 November (12) and have since fuelled several reports suggesting they're back together.
