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 shoo[t] 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.
