CHEERS to the queen of cameos, Nancy O’Dell. The Access Hollywood anchor showed up on the series finale of Melrose Place (May 24) as a witness to the attempted murder of Amanda (Heather Locklear) and Peter (Jack Wagner). The same week, O’Dell played a TV weathercaster on Charmed (May 26). It would have been a quick cameo, except in the episode’s Groundhog Day plot, O’Dell’s brief stint was repeated over and over. Hey, come to think of it, we’ve also seen O’Dell recently on Beverly Hills, 90210 and Sunset Beach. All four of these shows are Aaron Spelling productions. Don’t tell Tori!
