Wow. Wow. Wow.
Kanye is straight-up INSANE!!!!!
Britney Spear's two biggest fans were in the audience on Friday night at her Femme Fatale tour stop in New Orleans:
Her sister Jamie Lynn and her niece Maddie! Cuteness!
The pair were joined by Poppa Spears and Jamie's brother Bryan, each of which took turns holding little Maddie, who was spotted wearing big headphones to dull out the loud noise!
A family affair! But where was Momma Spears we wonder???
