Christie Brinkley may be walking around with a cast after after suffering a broken arm during "Dancing With the Stars" rehearsals, but Wendy Williams isn't convinced the injury's real.

On Monday, Williams said the fall her "personal friend" sustained looked "fake as hell," suggesting that Brinkley "plotted" to get her daughter Sailor Brinkley-Cook on the show to give the 21-year-old's modeling career a "leg up."

"In my opinion, I think what Christie did was she signed up for 'Dancing With the Stars’ knowing that she’d put her daughter Sailor in there," Williams said on her talk show.

Brinkley, 65, pushed back against Williams' "stunning" accusations on "The Talk" Thursday, showing the panelists her X-rays and badly bruised right arm as proof.

"My message to Wendy is: It’s so much more fun to be kind. Try it," Brinkley said. "It can't feel good to try to hurt other people. If it feels good, something's seriously wrong."

Brinkley said she was shocked to learn that Williams accused her of faking an injury because they share a friendship, adding that she stood by the talk show host's side during her split from husband Kevin Hunter earlier this year.

"Wendy Williams started this rumor, which was stunning to me because I’ve been on Wendy’s show a couple of times," Brinkley told co-hosts Sharon Osbourne, Marie Osmond, Eve, Sheryl Underwood and Carrie Ann Inaba. "I thought it was a mistake when somebody said she was doing this."

Brinkley added on Instagram, "Anyone who follows me pretty much knows I don’t usually 'clap back' but if you mess with my 'kids' watch out!"

On Tuesday, Williams, 55, had apologized to Brinkley for hurting her feelings, but added that her "opinion still stands."

Talk about Brinkley's injuries began after an ABC video clip showed Brinkley rehearsing five days before Monday's premiere. In the clip, she stumbles against her partner's foot and falls to the floor, apparently breaking her arm.

“While rehearsing for the premiere… Christie Brinkley suffered injuries which required surgery to her wrist and arm," a statement from ABC issued to USA TODAY read. "She is unable to continue her planned participation on the show. Keeping it all in the family, her daughter Sailor Brinkley-Cook, a Sports Illustrated model, has chosen to quickly step in with hours to learn the entire routine and will compete in her mother’s place for the remainder of the season."

Sailor and pro partner Valentin Chmerkovskiy went on to earn an 18 out of 30 for their stylish fox trot, which she learned in just three days of training.
