While she didn't disclose the details of the encounter, she previously said they got into it on The Talk. "I didn't get on with him at all," Sharon told Larry King, explaining that Ashton had a "bad attitude" because she mispronounced his name. "He was pissed. And he comes on with an attitude, and he goes, 'What have you done in this industry?' I was like, 'Kid, don't start with me. 'Cause I'm gonna eat you up and shit you out.' I was just like, 'You don't know what you're dealing with, kid.'"

The encounter apparently happened years earlier when a then-11-year-old JoJo asked Candace for her autograph and was denied. Candace apologized for snubbing her and said she felt "crummy" for making a child feel that way.

Teresa said their PR people were trying to get them to take a pic together in 2017 when she overheard Sofía allegedly saying she didn't want to pose with her. "I didn't want a picture with her ... She was the most rudest woman I've ever met," Teresa said of the Modern Family star. "You're so not a humble person. You forgot where you came from. It's not like she, you know, started out being on the top. She came from, you know? [...] She was so not a down-to-earth person. So, not a fan of hers."

After receiving words from JoJo's mom, Justin apologized and said he didn't mean to be "malicious or mean-spirited." He just didn't like the design.

According to Access, James explained in a video that Ariana started following him on Instagram after he posted something from one of her shows. Then she unfollowed him mere hours later. “I messaged her back, and I was like, ‘Hey, did I do something wrong?’ And she literally was like, ‘Hey, babe, I saw a lot of angry tweets from my fans, and I would never want to disappoint them, so I unfollowed.'” James said at the time that it was "really disappointing" to see, but he's since expressed regret for calling her out.

He recalled meeting the Friends actor at a party with his wife, Heidi Montag, in 2009. "Phoebe approaches, which was a little shocking since nobody had talked to us at all at the party," he remembered. "Right in front of me, she tells Heidi, she needs to get away from me as fast as possible because I'm going to murder Heidi, and I have the eyes of a serial killer." He continued, saying, "Heidi waits to see if this is a joke — maybe this is a bit, maybe this is a hidden camera party. No laughs — she just walks away. And that right there is the rudest moment I've ever encountered with a human being."

Bethenny said of all of her guests, Lisa "stood out as the person who wanted to be there least out of the entire run." "I was asking her basic questions, and you could tell she didn't wanna be there, which does make two of us," she stated.

I know how to approach another celebrity. Charlize was just mean. I'm just being honest." Charlize questioned the validity of InTouch's story and said, "I'm not an eye-roller, but I would be like, 'Fuck off.'"

James said he was at a U2 concert with his wife when Pierce came up and shoved right through them. "Literally, I've never felt anything like it. This arm went on mine and just pushed me out of the way. And I looked at him, and he didn't even glance at me. He just moved back into his area — just like that." When guest Khloé Kardashian suggested that Pierce might have just been drunk, James replied, "Maybe he's just a bit fucking rude."

“I was a fan at that time, a long time ago, and I went up to her because she was at a Van Halen concert, and I said, ‘Oh my God, I think you’re a beautiful singer, blah blah blah,’ and she just went like [she made an over-her-head motion], ‘Yah, whatever.’ She gave me the cold shoulder and I thought, ‘Bitch, I’m a fan! You can’t be nice to me?’ You know?”
