Martha Stewart Defends Mariah

Despite a report on PerezHilton.com that said Mariah Carey kept everyone waiting for her for a Macy's commercial shoot, Martha Stewart has taken to her official Twitter page to defend the singer.

She writes: "by the way mariah did not keep us waiting as reported by perez hilton the shoot is on schedule thanks to director Barry sonnenfeld's complete command."

Perez's sources had said that Mariah had pulled a diva turn by keeping fellow celebs Martha, Donald Trump and Jessica Simpson waiting for her by being hours late to the shoot.
