*Dang, we really hate to see this. It’s messy and it’s just not a good look.

What’s happening is that brothers Charlie Wilson and Ronnie Wilson are battling it out over exactly WHO is The Gap Band. Or more precisely, who can make money off the name.

The situation has gotten to the point that Ronnie filed a lawsuit claiming Charlie is derailing his efforts to launch a comeback tour.

In the docs, obtained by TMZ, Ronnie says he recently booked 2 big gigs — one at B.B. King Blues Club & Grill in NYC, and another at Howard Theatere in Washington, D.C.

Ronnie says after he sealed the deals, Charlie — who left the band in 2009 — had his people step in and somehow interfere with the bookings. Ronnie says both venues pulled the plug.

The elder Wilson points out his band existed for years before kid bro Charlie joined in ’72.

According to Ronnie, he says his new Gap Band stood to make more than $20k from the 2 gigs. Specifically, he’s suing for damages and wants the court to block Charlie from interfering with future bookings.
