John Legend can do know wrong.
Seriously, we don't know how the All of Me singer delivers a killer performance EVERY SINGLE TIME!
Check out the Legend's patriotic performance (above)!
So while some celebrities enter rehab for an addiction to alcohol or drugs, David Duchovny checked himself in to rehab last month for an addiction to sex.
Hey now…that sounds kind of dirty!
Don't worry, he was there with his wife, Téa Leoni, so we're sure he kept things in…Czech!
Let's hope he doesn't relapse, like some other rehab alums we know.
That sounds like it would be messy!
