It seems like Selena Gomez just can’t quit Justin Bieber – and vice versa.

The former lovebirds were spotted several times over the weekend, sparking rumors that they might be getting back together – again.

Gomez, 21, and Bieber, 20, met up in McAllen, Texas, on Friday for breakfast and shopping.

Lori Johnson, manager of Don Pepe’s McAllen Mexican restaurant, told PEOPLE the couple went into the restaurant with a bodyguard around 10:30 a.m. for breakfast and left about an hour and a half later.

“They were kissing,” Johnson added. “They were sitting next to each other hugging and kissing in front of the staff. They weren’t hiding it and seemed to be boyfriend and girlfriend.”

According to PEOPLE, the duo next visited the Royal Perfumeria shop. Owner Lydia Gonzalez told the magazine: “They came in together for about five minutes and he wanted to smell the Givenchy cologne and he wanted Obsession. And Selena was just browsing and looking at the fragrances for women. They were both polite and nice.”

They were also reportedly spotted hanging out at a Starbucks.

Gomez, who was in town to perform for the first time since her rehab stint, tweeted a photo of her enjoying a drink.

“Hidalgo, I’ve missed this :) ill see you sooon,” she captioned the picture.

The “Come and Get It” singer performed at the 2014 BorderFest concert at the Hidalgo State Farm Arena on Saturday evening. She rocked a sizzling white ensemble with a midriff-baring top, a sheer mesh skirt and knee-high lace up stiletto boots.

“Reunited and it feels sooo good :) TX always makes me proud #littles #realmexicanfood #home,” she tweeted with a photo.

Bieber fueled speculation that he went to show his support for Gomez when he tweeted Sunday: “Saw a great show last night :)”

Before the concert, the two singers also visited Xtreme Lazer Tag in McAllen, according to E! News.

“They showed up, played some laser tag and had a lot of fun,” an employee told the gossip website.

They were also spotted leaving Action Dance Studio, where they spent a couple hours in a private rehearsal space.

According to Cosmopolitan, Bieber also dedicated a song to Gomez when he unexpectedly stopped at this year's South by Southwest Festival in Austin, Texas on Sunday where he performed an acoustic set at Banger's Sausage House & Beer Garden.

During his performance, Bieber sung his hit "As Long As You Love Me," saying "this next song goes out to my baby," while gazing at Gomez, who was standing in the wings of the stage.

All this hanging out comes days after Bieber reportedly walked out during a four-and-a-half hour videotaped disposition stemming from a lawsuit against him after he allegedly told his bodyguard to rough-up photographer Jeffrey Binion.

The session reportedly became heated with Binion’s lawyer started asking questions regarding Gomez, TMZ reported.
