Vanessa Williams: I Am 'World's Coolest Mom' | Miley Cyrus, Vanessa Williams
Vanessa Williams may star in her own hit sitcom, but becoming the "world's coolest mom"? Now that took a little help from Miley Cyrus.

The Ugly Betty star said she's going to play Hannah Montana's publicist in a version of the Disney Channel show – and her daughter is very excited – during Lincoln Center's Annual Spring Gala Wednesday night.

"My 7-year-old, [Sasha Gabrielle], is into [Miley's] music," Williams told PEOPLE after the event, adding that the deal is so new, she "hasn't even signed yet."

As for the role – playing Cyrus's pushy publicist – "[She] thought it was the coolest thing in the world," said the 45-year-old actress, "and that I'm an awesome mom!"

Disney could not confirm the casting news.
