Andy clarified he meant Randall's last name, and Lala laughed. "I thought you meant get adult-like and maybe go by my real name!" she said. Lala's real name is Lauren.
"Of course," she added. "I so want to change my last name and rep my man so hardcore."
Well, there you have it. Lala Kent will soon be a very proud Lala Emmett. But it's what happened next that left Andy absolutely speechless.
Last season, Lala made headlines after she was seen sucking milk from an actual baby bottle. She confessed to her co-stars she did that every night before going to sleep because it "soothes" her.
"What is happening with sucking on the baby bottle?" Andy asked. "Still happening?"
"No," she replied. "Now I just suck on other things."
After about 10 seconds of giggling uncomfortably, Andy said, "Alright, I'm gonna leave it there. I had a really good comeback, but I feel like it's over the line."
Lala then moved on to talking smack on co-star and former-friend James Kennedy. A few seasons back, Lala and James were the villains of the show. They teamed up on body-shaming co-star Katie Maloney -- comments Lala has since apologized for profusely.
But James doesn't seem to have the same remorse. As recently as two episodes ago, he shouted at Katie in a drunken stupor, "Don't even get me started on you, darling! Those shorts aren't working for you, babe. She shouldn't be wearing those shorts. They're not very flattering. Lose some f--king weight!"
Lala was disgusted with his behavior, telling Andy, "It makes me sick. I feel like we had learned from that the first time, and clearly I was the only one that realized that that was absolutely disgusting."
"He's so-- It's the craziest thing! Like, how can someone make the same mistake so many times?!" she added. "Like, what is happening?! I wanna study his brain. And everyone's like, 'He only does it when he drinks.' Like, so every hour of the day? I don't understand."
Andy then played a sneak peek of next week's episode of "Vanderpump Rules," where Lala confronts James' girlfriend, Raquel Leviss, about all his "alleged" cheating. Lala knew what the conversation entailed, but she hadn't seen Raquel's confessional interview, in which she said, "[Lala] heard one thing that she didn't like, and boom, she dropped the dad card." Lala lost her father unexpectedly in April of this year.
When "WWHL" cameras panned back over to Lala, she was stirring. She exhaled deeply and said, "Just when I think she can't get any dumber, I lose more brain cells."
The next new episode of "Vanderpump Rules" will air Sunday, December 23 at 9 p.m. on Bravo.
