Celebrity News:

Jennifer Lopez played a concert at Madison Square Garden last night, and her most loyal fans were part of the audience. And they're related.

TMZ caught Mama Lopez, J.Lo's younger sister Lynda, and a few family friends leaving the concert last night, almost all of them sporting Jennifer's giant face on their t-shirts.

Did Lynda learn nothing while working for the Style Network? You're not supposed to wear the t-shirt of the artist you're seeing to their own concert! Then again, they might have to.
