(TMZ) -- Beyoncé and friends got in formation for some fun at the roller rink ... and it's clear she's not letting the twins keep her from having a good time.
Bey and JAY-Z showed up at World On Wheels in L.A. Friday night with eight other friends just a little before midnight ... and TMZ was told she left her VIP area and went straight to the rink to skate with the common folk.
A source at the place told TMZ that only lasted for a bit -- because her crew was getting hounded -- so they shut the place down for a private skate sesh around 12:30. It's good to be the Queen.
TMZ was told Jay didn't put skates on ... but we know he's enjoying all the activities.
