THINGS are getting hairy between Sherri Shepherd and Wendy Williams!

The two talk-show divas have made nice on camera, but insiders say behind the scenes they’re dissing each other’s wig collections.

“Sherri pretends she doesn’t care about Wendy’s wigs,” a source told The ENQUIRER.

“But she was overheard saying that her styles are more natural and practical, while Wendy’s line seems to be geared toward young girls and drag queens. Sherri would never say it to Wendy’s face of course, but it was a clear jab.”

Shepherd, 46, often mentions her 12-piece collection for LuxHair while co-hosting “The View.” It’s already available on, QVC and other Internet sites.

Meanwhile, 48-year-old Williams’ line, Wendy Williams Hair World, will launch this summer. The former radio DJ – who’s been diagnosed with a thyroid condition that can cause hair loss – is known for her fabulous hairpieces and extensions.

DESPITE their business rivalry, Williams allowed Shepherd to plug her wig line during a June 17 appearance on “The Wendy Williams Show.”

“Wendy heard about Sherri’s nasty comment afterward, but she wasn’t that concerned,” added the source. “She was actually more upset that she didn’t know about it sooner because she would have loved to confront Sherri on the air.

“Besides, Wendy’s not worried about her wig line flopping because she considers herself an expert on all things hair-related. She says the proof is in the pudding – and her hair is always impeccably styled for TV. But that’s not true for Sherri!”
