Grimes Reveals Her & Elon Musk's Son Uses Her First Name & Not Mom

Grimes and her baby boy are on a first-name basis! The musician revealed that her and Elon Musk's 1-year-old son doesn't call her "mom" or "mama" and instead uses her real name only – Claire. Grimes explained in a behind-the-scenes video for Vogue ahead of her Met Gala appearance earlier this week that she isn't sure where the little one got the idea but admitted that she doesn't mind because "mother" isn't a title she's quite comfortable with.
