Selena’s man treats the audience to some classic songs — and shows some PDA with her onstage!

Justin Bieber has been treating his girlfriend Selena Gomez so well lately, and he took his affection to the next level by crashing her July 24 concert at The Pacific Amphitheatre in Costa Mesa, Calif. — he hugged her and sang in front of a huge crowd!

Justin, 17, joined Selena, 19, to sing a medley of hits, including his own “Favorite Girl” and a cover of Justin Timberlake‘s “Cry Me A River.” While he was doing his thing onstage, Selena was too cute dancing along on the side!

Later, Justin took to Twitter to congratulate Selena on a great show, writing, “@selenagomez u did great tonight. proud of u.”

What do you think, HollywoodLifers — could this be the best concert that has ever happened?
