The battle is on. After months of speculation, Swizz Beatz and Timbaland have agreed to face off in a beat battle.

On Thursday (July 13), Swizzy appeared onstage during the Conor McGregor and Floyd Mayweather press conference in New York, where he decided to issue a challenge against Timbo. Later, he reiterated the challenge in a social media-shared clip.

“Timbaland don’t want any smoke,” said Swizz. “Tell him he can get this too. Don’t talk behind my back.”

One day later, Timbaland responded in a video of his own, which was soundtracked by the “Game of Thrones” theme song.

“Swizz,” he said. “You have woken up Tim Mosely. Challenge accepted. I’m with the smoke. That’s right. You hear that ‘Game of Thrones.’ You have woken up the king.”

Shortly thereafter, Swizz shared a video of himself on Instagram. His caption was simply: “#imwiththesmoke.”

Swizz Beatz is coming off another high-profile battle. In February, he faced off against Just Blaze at a special event, where he shared an unreleased JAY-Z, DMX, Nas, and Jadakiss collaboration.

“We just doing it for the culture,” said Swizz. “We’re just vibing. We’re just going. This is something that hip-hop needs. I don’t got no pre-made beats. Everything I’m doing is right off the cuff. We’re going to go back and forth with our hits. We’re going to just have fun and let the people have fun.”

At the time, Just Blaze said that other producers would likely battle as well. According to him, those potential matches included The Alchemist vs. Havoc, Harry Fraud vs. Buckwild, and coincidentally, Timbaland vs. Pharrell.

There is no word yet on when the Swizz vs. Timbo battle will go down.
