Jay-Z and Kanye West already have two potential challengers to their upcoming [article id="1655640"]Watch the Throne.[/article] In an interview with U.K. radio personality Tim Westwood, [artist id="2545682"]Drake[/artist] announced that he and [artist id="510062"]Lil Wayne[/artist] are working on a joint album of their own, and he took a couple of jabs at Hova and Yeezy's project in the process.

"I'll be on [Tha Carter IV], though ... We've done a great song ... and then we're going to do another one, and another one," the Young Money MC said. "We still got to do that album. I heard some other guys are coming out with an album, too. There's two other rappers that are coming out with an album together. ... I don't know where they got that idea but ..."

Westwood probably knew Drake was referring to Jay-Z and West but played into the coy act, saying, "I'm very slow; can you just break it down a bit simpler for me please?"

Then Drake continued, "I just caught wind of it through the grapevine, that there's some other album coming out with two guys rapping on it too."

"Oh, those two ... you mean the older guys," Westwood said.

"Oh, I didn't say that," Drake replied. "They look young to me ... in their movements."

West and Drake haven't been as close as they seemed back in 2009, when Yeezy directed the up-and-comer's [article id="1614100"]video for "Best I Ever Had."[/article] The Toronto rapper recently was left off of the final version of [article id="1653947"]West's "All of the Lights,"[/article] but he told Shade 45 radio that he was OK with it.

Drake's sophomore album, Take Care, is due later this year.
