The 21-year-old singer couldn't help but comment on the 22-year-old actress as he left the annual event Monday evening. Bieber was headed to Rihanna's after party at Up & Down club when he mischievously told reporters, "Selena looked gorgeous at the Met Ball!"
Gomez stunned in a Vera Wang gown at the fundraiser and accessorized with several white orchids in her hair. The actress attended the same after party as Bieber, and reportedly "exchanged some words" with the singer at the fête.
Bieber and Gomez were an on-and-off couple for several years, and the latter admitted to still having love for her ex in December 2014. The singer is often linked to models Kendall Jenner and Hailey Baldwin, while Gomez is rumored to be dating Russian DJ Zedd.
Bieber previously shared his admiration for Gomez by posting a photo of the actress with the caption "Most elegant princess in the world" on Instagram in March 2014. Gomez seemed to reference the incident by writing "Felt like a princess once again" on a Met Gala snapshot.
