The Wendy Williams Experience hasn’t been heard on Power 99 for a couple weeks now. Williams was on vacation last week but was heard Monday and yesterday on her New York homebase at 107.5 WBLS, but Power 99 continued to play music. Last week, Power 99 spokeswoman Loraine Ballard Morrill told us that Williams show was on vacation and there was nothing to any rumors of a problem with Power 99. Morrill did not return e-mails or phone calls Tuesday about Williams’ absence. Williams vaguely hinted at some type of problem with Power 99 on her Monday show, but her spokeswoman did not return our request for comment. A woman who answered the phone at Williams’ New York studio yesterday said she was working while on vacation would still be taking off a few more days and should be back on Power 99 next week. Asked of Williams’ remarks regarding a problem, the employee said Williams probably wouldn’t want to say any more about it.
