She’s been hobnobbing with celebrities and modeling designer outfits since she was born, and before she was old enough for kindergarten she appeared in Mom’s Peabody-award-winning Lemonade.

The song is a bonus track that only popped up when 4:44 hit iTunes last night, so that’s why we’re just hearing it now.
