-_- Video== ''Justin Bieber'' dedicates song to his {baby} ''Selena Gomez'' as pair appear to finally confirm romance ???

If you thought their saucy dance moves weren't proof enough that Justin Bieber and Selena Gomez are back together - then you're very much mistaken.

Bieber dedicated a song to his "baby" during a surprise performance to the pretty brunette in Texas.

The 20-year-old singer turned up at the Banger's Sausage House and Beer Garden in Austin for the South by Southwest festival, and sang his hit As Long As You Love Me.

While his private life is swamped in controversy , the hitmaker looked towards Selena - who was standing in the winds - and told the crowd: "This next song goes out to my baby."

After Bieber's romantic gesture, the pair - who have been dating on/off since 2010 - reportedly hung out together in the beer hall for an hour after everyone left the venue.

A source told Us Magazine: "Justin and Selena were together the whole time. Sitting together, hanging out, and very friendly together."

The duo, who split up earlier this ye ar, have sparked rumours they have rekindled their romance recently after they were spotted enjoying a romantic dinner in Texas last weekend.

However, Selena's parents are reportedly against the pair reconciling as they believe Biebs, who has had a number of run-ins with the law recently, is responsible for driving Selena to rehab earlier this year.

Selena was admitted to Dawn at The Meadows recovery centre in Arizona on January 5, and spent two weeks at the facility, which treats people aged 18 to 26 years old who are "struggling with emotional trauma, addiction or dual diagnosis concerns."
