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.
