Paula Abdul will pop up on “Dancing With the Stars.” The former “American Idol” judge was overheard at Douglas Hannant’s fashion show revealing she’ll “perform and sing” on the ABC series for November sweeps. Abdul added she’ll do segments for NBC’s “Today” that will be “inspirational.” She has been a Fashion Week fixture, appearing at shows for Carlos Miele, Emerson and Chado Ralph Rucci. “I’ve spent the last decade as a judge. Now I love what I’m doing,” she told a pal.
