The 24-year-old actress and 27-year-old singer looked the picture perfect couple as they packed on the PDA at the music festival Saturday in Indio, Calif.
Gomez, who wore a blue, floral-patterned sundress, shared a photo on Instagram of herself and The Weeknd that quickly racked up over 6.5 million likes. Fans also captured the couple sharing a kiss and enjoying some curly fries.
"She wants the world to know they're together," a source told Us Weekly. "She only does that when she's really dating someone."
"The Weeknd was holding Selena from behind while dancing together," an insider told Entertainment Tonight.
Gomez and The Weeknd were first linked in January following the singer's split from model Bella Hadid. The Weeknd posted a first picture with Gomez this month after attending rapper Belly's birthday party in Los Angeles.
"Selena and The Weeknd were very sweet together and mellow," E! News reported at the time. "They took selfies and then cuddled up together. They were really focused on each other and look very serious and in love."
