John Rich -- We Love Gwen Stefani

Country star John Rich says there's no need to pick sides in the Blake Shelton, Miranda Lambert divorce ... he's just stoked Gwen Stefani is now in the picture.

The Big & Rich singer was leaving Legends Corner after the CMA Awards Wednesday, when our photog asked about the turn of events now that Blake is dating Gwen.

Turns out John is a HUGE Gwen Stefani fan, so he was actually borderline excited.
