Taylor Momsen's Teen Mom

It's no surprise "Gossip Girl" star Taylor Momsen is often dressed inappropriately for a 16-year-old ... because her mother dresses younger than she does.

Decked out in Miley Cyrus shades, a Selena Gomez jacket, a Demi Lovato t-shirt, Dakota Fanning pants and a pair of Mary-Kate Olsen boots, Taylor's adult mother Collette accompanied her more matronly-attired teen spawn to the NYC set of her TV series on Wednesday.

Remember when you were embarrassed by your mom in high school?
