Mariah Carey has appeared on a series of ads for Macy's. The first two were directed by Oscar-winning director Barry Levinson and launched in March 2008. On "Carlos and Mariah," we can see Mariah singing along as Carlos Santana plays the guitar. "The New Guy" introduced Calvin Klein model Gabriel Aubry to the Macy's team, prompting hilarious reactions from both Mariah and Martha Stewart. A Spanish-speaking version of the "Carlos and Mariah" ad was also released.
On September 2009, Macy's and Feeding America launched "Come Together," an innovative awareness and fundraising campaign that aimed to feed 10 million people suffering from hunger. The Come Together campaign launched with one of Macy's famous celebrity TV spots featuring the retailer's "star" designers. The commercial, directed by Barry Sonnenfeld, featured an all-star cast including Mariah Carey, Jessica Simpson, Queen Latifah, Usher, Martha Stewart, Emeril Lagasse and Tommy Hilfiger. "It's great that Macy's is doing this because it's going to draw attention to the situation and hopefully other people will follow suit," Mariah Carey said.
