Chrissy Teigen still gets starstruck over her favorite celebrities. During an appearance on The Tonight Show Starring Jimmy Fallon [1] on Tuesday, the model, who is expecting her second child [2] with husband John Legend [3], explained the hilarious and slightly mortifying way she greeted Beyoncé at the Grammys [4]. Even though she's interacted with the singer before, she couldn't help but drop to her knees when she came face to face with her. Aside from literally bowing at her feet, she also referred to Bey as her "queen." LOL!
