The two have been rumored to be talking again and Bieber got noticeably agitated when a lawyer in a Miami deposition asked him about Gomez.
"Don't ask me about her again," Bieber said again and again in video obtained by TMZ during a deposition regarding a case involving his bodyguards and a photographer, who claims he was assaulted and robbed by the guards.
Just hours after the deposition, Bieber -- who has had a rough year that's included an alleged DUI and other legal matters -- and Gomez were reunited for an entire weekend in Texas.
While in town for South by Southwest, Gomez and Bieber began their weekend with a private breakfast/lunch together at Don Pepe's McAllen Mexican restaurant on Friday in Austin, Texas.
The couple who first split in 2012 has been on and off ever since.
Don Pepe's manager Raul Mares said the couple's people called around 10:30 a.m. that day asking for a private meal.
After at first saying "No," Mares called the restaurant's owner and they said it was OK. The duo came in around 11 a.m., he said.
"It was Selena, Justin, his bodyguards and two other people," he told ABC News. "One looked like a friend and the other maybe a manager, someone who pays the bills."
Mares said the group came in two SUVs -- one red and the other black -- and that four bodyguards waited outside in the cars for the singers.
"They came in through the side door," Mares said. "Selena was pretty cool. Justin didn't say much. They were really affectionate, Selena was on his shoulder. They look like boyfriend and girlfriend."
He said there was some kissing.
At around 7 p.m., the pair went to Action Dance Studio in McAllen and hung out in a private room for two hours.
Yair Cruz, who owns the studio with his wife Alexandria, said he couldn't say for sure whether the duo were back together, but it looked like they were happy to see each other after a long time apart.
"We were honored to have them here at the studio," he said and that the studio never considered charging the famous couple. "They were really nice to us."
On Saturday night, Gomez performed in Hidalgo and reports had the "Baby" singer, 20, on hand that night to support her. He even tweeted about the show the next day.
"Saw a great show last night," he said.
The weekend didn't end there. Cosmopolitan magazine reported that Bieber performed a surprise acoustic set at Banger's Sausage House & Beer Garden.
The magazine reported that he dedicated "As Long As You Love Me" to Gomez -- who was there -- saying "this next song goes out to my baby."
