[Embedcode {}] Selena Gomez featured special guest and "best friend" Charlie Puth for her last U.S. date of her worldwide Revival Tour. The pair, who were once rumored to be dating, performed their hit duet "We Don't Talk Anymore" live for the first time at the Honda Center in Anaheim, California on July 9. Gomez, 23, commanded the stage looking stunning in a black thigh-high slit dress by Galvan with Giuseppe Zanotti heels while Puth, 24, played the piano dressed in a plaid shirt and jeans. "We Don't Talk Anymore," the third hit single from Puth's debut album, Nine Track Mind, was released in late January.
