The actress also opened up about her Comic-Con tips as she promoted her new film, 'The Lego Ninjago Movie.'
Someone apparently isn't too impressed with Mariah Carey's dancing recently.
ET's Kevin Frazier caught up with the cast of The Lego Ninjago Movie at San Diego Comic-Con on Friday, where Olivia Munn took the interview for an unexpected turn by showing off how she dances to Mimi.

"It's a lot of [this]," Munn said while showing off a few of the moves we've seen on her Instagram lately.
"Wow, Mariah! Did you change your hair?!" Munn's co-star, Michael Pena, joked, as the rest of the cast busted out laughing.
"It's more dancing than Mariah has done lately, if you saw what she's been doing lately," Munn said, defending herself. "Shots fired!"
"I think it's an accurate shot," Munn continued. "She was in Vegas the other day, and then she danced the next night, showing everybody that she really could dance, but there was one video that went viral of her not really dancing that much."
"Why do you hate Mariah Carey?" Kumail Nanjiani asked.
"I love Mariah Carey!" Munn insisted.

While Munn appears to have at least a little beef with Carey (it comes from a good place!), she couldn't stop gushing about her friendship with Ayesha Curry.
"We met maybe a year and a half, two years ago, and we just became instant friends, and I love her so much! She's one of the most down to earth, cool people. They're like, the best couple," she said of Ayesha and her husband, Golden State Warriors star Steph Curry. "They're a great family. I was so excited to see [the Warriors] get in this year. I remember I texted her the very first game, 'Like, you guys are winning this whole thing.'"
"It was so fun to watch it all just happen," she added.
But back to Comic-Con. Munn offered her co-stars a few pieces of advice as they navigate the convention.
"Wear pants that can turn into shorts, have a backpack and don't take everything that's free," she said, before declaring that The Lego Ninjago Movie is the best Lego movie yet.
"[The Lego Batman Movie] was the best Lego movie ever, and then our Lego movie came out, and now ours will be the best," she reasoned.
"It can only go up" Justin Theroux interjected.
"And it does," Munn asserted.
