Sharon -- who was wearing her wedding ring on the show -- laughed at her 31-year-old daughter's tweet, bragging that she has the best sense of humor. "In cases like this, what can you do but laugh?" the 63-year-old TV personality said. "[Kelly's] so funny. She loves her mom. She loves her dad so much."
Sharon dotingly added, "I'm always proud of my girl. What are you going to be mad? She's an adult."
However, not all of Kelly's four million Twitter followers found the message as funny as Sharon did. "Hate your father, not the woman. HE did this to your family ...Again. #SMDH #childish," one Twitter user responded to the tweet.
Kelly wrote back, "Are you in my family? NO YOU ARE NOT. YOU HAVE NO IDEA WHAT SHE DID! So keep your high-mighty opinions to yourself!"
A source close to Sharon told ET earlier this month that Ozzy's alleged infidelity has hit her hard. "Sharon has put up with a lot over the course of their marriage and there have been other dramatic things that have happened with them in the past, but this is the first long-time affair Sharon has found out about," the source said. "This is an emotional affair -- it wasn't just a one-time hookup. There are feelings there between Ozzy and this woman. This is a double life he’s been leading -- and that's what upset Sharon the most and made her leave him."
