La La Anthony may have a best-selling book about love and happiness, but that does not mean husband Carmelo Anthony is always on his best behavior. This week, during a televised game between the New York Knicks and Memphis Grizzlies, Anthony was caught on camera staring at a woman in the audience.

He even turned his head while walking away so that he could look back at her.

La La's top-selling book, “The Love Playbook: Rules for Love, Sex, and Happiness,” chronicles how she found love and success on her own terms. She notes that her friends turn to her for advice, but after Anthony’s inappropriate behavior, she may be asking for advice herself.

This is not the first time their relationship has been tested. Last January, the couple became the center of a media frenzy after Carmelo became upset with Boston Celtics star Kevin Garnett for allegedly making a comment about La La tasting like Honey Nut Cheerios.

La La later said Garnett never said that, and it remains unclear what the 36-year-old said to infuriate Carmelo, 29, but the Knicks forward said, "There’s certain things that you just don’t say to men, another man. I felt like we crossed a line, but, like I said, we both have an understanding right now; we handled it the way we handled it."
