Justin Bieber still may carry a torch for his ex-girlfriend Selena Gomez.

The exes both attended the Met Gala in New York on Monday evening. While not photographed together, Bieber did get a look at Gomez's stunning, white gown and loved what he saw.

"Selena looked gorgeous at the Met Ball," he yelled out his car window to fans and paparazzi as he pulled away from the curb.

The on-again, off-again couple first got together as far back as 2010 and made their first public appearance at the Vanity Fair party in 2011. The pop stars tried to make it work again last fall, but Bieber's friendship/relationship with Kendall Jenner seemed to get in the way.

The Met Gala tried to impose a "no selfie" rule, but Bieber managed to snap a couple photos with Cara Delevingne and Lady Gaga at the fashion extravaganza. Gomez also grabbed a sweet pic with Lily Collins, Vanessa Hudgens and a couple other gal pals.
