Beyoncé tagged along to see her hubby Jay-Z perform at the Coachella Music Festival in California last night…but somehow ended up joining him on stage.

Below, she sings sangs “Young Forever:”

QUESTION:
I know Beyoncé is SUPPOSEDLY on hiatus and all and Jay-Z is her man and all…
But, do y’all think she charged him for this performance?!

I mean, he’s HOV, I’m sure he could write her a check immediately following and all that. But when she performs with him I really wonder sometimes if she charges him or at least give him the “You My Future Baby Daddy” discount?
