Sharon continued, "She loves her mom and loves her dad so much. And listen, I'm always proud of my girl, and what are you going to do? Be angry with her because she loves her mom and dad, and she wants us to be together? She loves us. She can do what she wants. She is an adult." Watch!

Kelly wrote on Twitter with Pugh's rumored phone number, "Anyone looking for cheap chunky LOW-lights a blow out and a blowjob call.”

After Kelly tweeted out the Los Angeles number, it was disconnected. When some Twitter users criticized her actions, she responded, “are you in my family? NO YOU ARE NOT YOU HAVE NO IDEA WHAT SHE DID! So keep ur high-mighty opinions to yourself!”
