Hey kids, remember when we reported that Taco Bell issued an open letter to rap tycoon 50 Cent in which they suggested he change his name for a day to "79 Cent," "89 Cent" or "99 Cent" as part of their new promotional campaign?

Well, apparently Fiddy didn’t think that was such a cute idea. And he really didn’t like that the company went public with the concept without ever having him sign up for such a endorsement.

In fact, his lawyer says that “many customers believed that 50 Cent had agreed to endorse Taco Bell's products,” and therefore the bulletproof rapper is suing the taco chain for making him an unauthorized spokesman.

"Without seeking or obtaining Jackson's authorization, defendant Taco Bell made him the star and focus of its nationwide advertising campaign by using his name, persona and trademark to promote Taco Bell's business and products," says his lawyers

And they do have a point… 

"We know that you adopted the name 50 Cent years ago as a metaphor for change,” read the open letter. “We at Taco Bell are also huge advocates for change. We encourage you to 'Think Outside the Bun' and hope you accept our offer."

The legal papers were filed in Manhattan federal court Wednesday, and find 50 and his lawyers alleging that the restaurant chain engaged in some unjust promotion that resulted in his good name being tarnished. In fact, postings on 'blogs' chastised 50 for “selling out” by his apparent endorsement of Taco Bell.

"They crazy, man," 50 told radio personality Angie Martinez in June. "They sent a memo out. I don't wanna talk about it. We gonna take legal action. ... I guess they did that for promotional purposes. It's not good that they did that. They didn't have to do that.

"It gets uncomfortable at some point," he added about people trying to capitalize off his fame. "Especially when corporations do it to you. ... Like you gonna go to the store and beef with the kid at the counter."

He’s right, you know. 50 would never beat the crap out of some kid at a taco bell over what his bosses said. He’d have one of his G-Unit buddies like Tony Yayo do it and then rap about it on a dis track!
