E! News has learned that during a breakfast out in McAllen on Friday, the two were seen kissing in front of a few friends.
The group grabbed a quick bite at local eatery Don Pepe's, where we're told that Selena ordered pork chops with salsa and the "Beauty and a Beat" heartthrob opted for huevos rancheros.
There were around six people in the party total, including the famous pop stars.
According to a waiter, Selena was getting very close with the Biebs and "they were kissing" throughout the meal.
And while the two were in plain sight for all to see their PDA, Jelena wanted to stay as low profile as possible and refused to have their photos taken.
The former boyfriend and girlfriend were also spotted hugging at L.A. Imports, a floral shop, and Perfumeria La Versailles, where they browsed for a short while with a few of Bieber's closest pals.
She posted a selfie on Instagram with the caption, "Hidalgo, I've missed this :) ill see you soooon."
The Biebs also stopped by a SXSW party unannounced and brought the house down with a rousing rendition of "Baby"—which he dedicated to Selena. Wow!
