Though the NBA Finals currently rest at 3-2 in Boston's favor, legendary L.A. rapper Snoop Dogg has issued a public challenge to Boston Celtics fans -- put up or shut up.

The Doggfather has been going back and forth via Twitter with Boston Celtics fan and New Kids on the Block singer Donnie Wahlberg for the past week, but in a recent video, he upped the stakes, challenging Wahlberg to bet $20,000 on the outcome of the NBA finals, to be donated to a charity of the winner's choosing.

"What it do, Big Snoop Dogg, Lakers fan #1. Wahlberg what it do? Y'all want that bet? Let's get it crackin'," Snoop said. "20 Gs to your favorite charity, Lakers beat the Celtics, that's what it do!"

In response, Wahlberg saw Snoop's challenge and raised him one Radio City Music Hall humiliation, daring him to settle the bet onstage at Radio City during NKOTB's performance there, later this week. "I'll pay for the flight, rooms & expense. The loser steps on stage in the other [team's] jersey to hand over the check!" wrote Wahlberg.

Game 6 of the NBA Finals takes place on Tuesday, June 15 at 9PM EST, in Los Angeles.
