The Weeknd — whose real name is Abel Tesfaye — posted a photo of Selena’s back as she paused to admire a painting at the Uffizi museum in Florence on his Instagram Story. The “Starboy” singer couldn’t help but admire his girl as she stared at “The Birth of Venus,” one of the most famous paintings in the museum, Hollywood Life reported.

It seems like they’ve gone Instagram official just shortly after they both followed each other on the social media site earlier this week. A fan Twitter account for the “Good For You” singer posted screen shots of their exchange — which makes up for Selena losing another follower earlier this month — The Weeknd’s ex-girlfriend Bella Hadid.
