Treating herself to an evening of girl power, Selena Gomez attended the Mrs. Carter World Tour concert by Beyoncé Knowles in Los Angeles last night (July 1).

The “Wizards of Waverly Place” dame brought a few of her gal pals to the Staples Center for the gig, and looked gorgeous in cut-off denim shorts with a sheer black top.

Selena was no doubt celebrating the announcement earlier in the day that her new single “Come and Get It” had reached the coveted #1 spot on the charts.

Gomez tweeted a heartfelt thank-you to her fans, stating, “This has been 1 of my proudest achievements & I couldn’t do it without everyone! So grateful.”
