Carmelo Anthony has already been caught looking at women other than his wife, La La Anthony, since the two wed, and on Monday night at the Metropolitan Museum of Art's annual Costume Institute gala in New York City, his eye wandered once again. The 29-year-old Knicks player was snapped giving Rihanna an interesting look at an after-party for the annual fundraising event. While Rihanna was posing for a photo, Anthony was seen in the background staring at her.

But who can blame him? The 25-year-old pop star stunned observers at the after-party in her sexy gold gown that showed off her back, midriff and part of her butt. Her appearance seemed intentional as she wore a piece of jewelry right above her derriere, which was likely meant to highlight her backside.

This is not the first time Anthony has looked at women who were not La La since the two got married. In February, during a televised game between the New York Knicks and the Memphis Grizzlies, Anthony was caught on camera staring at a woman in the audience. He even turned his head while walking away so he could look back at her.

Ironically, his wife has a best-selling book about love and happiness. “The Love Playbook: Rules for Love, Sex and Happiness” chronicles how she found love and success on her own terms. She has noted that her friends turn to her for advice, but after Anthony’s possibly inappropriate behavior, she may be asking for advice herself.
