Jay-Z Endorsing Limited-Run Line Of Yankee Memorabilia

Merchandise will include T-shirts, baseball caps and more to coincide with Yankee Stadium shows with Eminem next month.

If [artist id="1269"]Jay-Z[/artist] made the Yankee hat more famous than the Yankees did like he claims in "Empire State of Mind," now the rapper has the chance to prove it. He's partnered with the championship baseball team to produce a limited run of Jay-Z-endorsed memorabilia, from T-shirts to sweatshirts to fitted caps, to coincide with his and [artist id="502642"]Eminem's[/artist] performances at Yankee Stadium next month.

The shows are scheduled for September 13 and 14 in the Bronx; the pair will also perform September 3 and 4 at Detroit's Comerica Park. The co-branded merchandise goes on sale beginning August 30 at Yankee Stadium and will be on sale until September 14.

Eminem spoke to Billboard.com on Friday (August 27) about the joint performances and said there won't be any one-upmanship going on between himself and Jay-Z. (Sorry, Tigers fans, sounds like there won't be any Eminem/Detroit memorabilia available.)

"Nah, I don't think it'll be anything like a competition," Eminem said. "For the most part, me and Jay just want people to come out and have a good time. We want them to enjoy the music."

The Detroit MC was reserved when pressed for details regarding the event. He wouldn't confirm set lists, guest appearances or whether he and Jay-Z would take the stage together at the same time. The pair collaborated once in the past on Jay-Z's "Renegade," which Eminem produced for the Brooklyn rapper's The Blueprint album.

"I don't want to get into it too much," Eminem said. "I don't want to give anything away. But ... I think it'll be good.

"Hopefully it'll be songs that everyone is familiar with," he added.
