As reported by AOL Music, Jennifer Lopez has found herself in the wrong place at the wrong time. The entertainer is currently serving as the celebrity face of Fiat, but little did she know she would soon come under some serious fire for endorsing the Italian car company.

Yesterday (Jan. 12), non-profit advocacy group United Against Nuclear Iran (UANI) publicly challenged Lopez and her ties to Fiat -- a company the organization alleges has direct ties to Iran's illegal nuclear missile program.

The president for UANI addressed the following statement to Lopez, "By endorsing Fiat, you are serving as a spokesperson for a company that freely does business with a regime that is developing an illegal nuclear weapons program, financing and sponsoring terrorist groups including al-Qaeda, has killed American and NATO soldiers and is recognized as one of the world's leading human rights violators."

The letter explains that Iveco, a Fiat subsidiary, "produces vehicles that are reportedly used by the Iranian regime as platforms to stage gruesome public executions." This isn't the first time J.Lo's Fiat endorsement deal has landed her in hot water. She shocked viewers with her blatant product placement during her performance at the 2011 American Music Awards when she drove up to the stage in a Fiat 500.

Lopez also came under fire for her misleading commercial with Fiat, in which she allegedly drives through the Bronx neighborhood where she grew up -- actually filmed in Los Angeles. She also faces a lawsuit by Bronx-bred graffiti team TATS Cru, who are suing Fiat and the singer for featuring their mural in the commercial without permission.
