Selena Gomez makes her post-rehab comeback

Selena Gomez has taken to the stage for her first performance since entering rehab… and she’s never looked better!

The 21-year-old, who voluntarily checked herself into a recovery centre in January to deal with emotional issues, burst back on to the stage at the Borderfest concert in Hidalgo.

It came just hours after she was spotted with her on/off/on/off/on/off/on/off boyfriend Justin Bieber in her native Texas.

In fact the pair are reported to have spent time getting hot and sweaty, busting their best moves in a dance studio after being seen hugging in a Dallas flower shop on Friday.

And it could be that sexy Selena had decided to treat Beebs to a private showing of her big comeback, where she sizzled in an all-white number.

The outfit perfectly showed off her best assets, with a cut out bra top that framed her midriff and a sheer skirt over her toned pins.

The Wizards of Waverly Place actress vamped the number up with laced-up knee high boots while wearing her hair in long, loose curls.

And she was glowing with a deep tan and radiant white smile.

The romantic reunion with her ex came after bad boy Bieber tweeted an Instagram picture of the brunette bombshell at an Oscar party under the caption: “Most elegant princess in the world..”
