Selena Gomez is back on the stage and looking better than ever.

The 21-year-old pop star performed at the 2014 BorderFest concert at the Hidalgo State Farm Arena in Texas on Saturday evening, marking her first show since her stint in rehab earlier this year.

The “Come and Get It” crooner rocked a sizzling Bryan Hearns white ensemble and flaunted her enviable figure in a midriff-baring top, a sheer mesh skirt and knee-high lace-up stiletto boots. She wore her long curly locks down and finished the sexy look with plum lips.

Gomez expressed her excitement to be back home in Texas and shared a sweet hugging snapshot on her Instagram account.

“Reunited and it feels sooo good 🙂 TX always makes me proud #littles #realmexicanfood #home,” the brunette beauty captioned the photo.

It’s been an eventful few days for the Texas native after reuniting with Justin Bieber in her home state.

“Saw a great show last night :)” Bieber tweeted on Sunday morning, fueling speculation that he was indeed showing his support for Gomez.

The brunette beauty was spotted with the 20-year-old, his bodyguard and several other pals on Friday in McAllen. E! News exclusively learned that the group enjoyed breakfast in the morning at local eatery Don Pepe’s and did their best to keep a low profile.

According to the restaurant owner, the possible on-again lovebirds didn’t want to take any photos during their meal.

We’re told that Selena ordered pork chops with salsa, while the “Beauty and a Beat” heartthrob opted for huevos rancheros.

The beautiful pair also went to L.A. Imports, afloral shop, where they were seen hugging and talking about flowers. They also made their way to Perfumeria La Versailles, where they browsed for a short while.

Before Gomez’s concert on Saturday, the two singers visited Xtreme Lazer Tag in McAllen.

“They showed up, played some lazer tag and had a lot of fun,” an employee tells E! News.

Gomez will perform on Sunday at the Houston Livestock Show and Rodeo.
