WATCH: Beyonce Drops Out of Coachella Due to Pregnancy, 'Following the Advice of Her Doctors'

The "Can't Keep My Hands to Myself" singer kept it cool and casual for the concert, rocking a pair of light-wash skinny jeans, a white T-shirt, sneakers and sunnies, while her beau amped opted for a patterned black top, black trousers and kicks that looked almost identical to Gomez's.

According to an eyewitness, at one point, "The Weeknd was holding Selena from behind while dancing together."

But they certainly weren't the only ones dancing -- fans on social media shared a number of pics and videos from the 24-year-old rapper's epic set, a preview of his Bird's Eye View tour, which kicked off earlier this month and continues until July.
