Carli Mauer is the young model and college student who made her debut on MTV’s Siesta Key during season three. Mauer was introduced in the 14th episode as one of Garrett Miller’s personal training clients. In the narration, she was also described as someone Miller had “hooked up with on and off in the past.”
MTV teased ahead of the upcoming episode, premiering on August 4, that Mauer’s presence would be part of the storyline. Miller’s girlfriend, castmate Kelsey Owens, will find out that Miller is still training an “ex-fling.”
Here’s what you need to know:
1. Kelsey Owens Confronted Carli Mauer at a Halloween Party to Demand She Stop Flirting With Garrett Miller
Mauer’s debut appearance on Siesta Key coincided with a Halloween party in which several exes were in attendance, such as Juliette Porter’s former flame Robby Hayes and Madisson Hausburg’s ex Ben Riney.
Mauer walked into the party wearing what appeared to be a Playboy bunny costume. In the clip embedded above, Miller noticed Mauer when she arrived and commented to his friends, “Damn, she walked in like a bolt of lightning.” Once Mauer found Miller, she gave him a big hug and Miller kept his arm around her shoulders as girlfriend Kelsey Owens looked on with a disapproving look on her face. Porter, who provides the narration, remarked in the voiceover, “Garrett just gave Kelsey a key to his apartment. So why is he acting like he’s about to go home with Carli?”
Later on the episode, Owens confronted Miller and accused him of flirting with Mauer. Miller admitted that he had a history with Mauer but insisted that any romance had taken place before he and Owens had gotten back together. He also denied flirting with Mauer at the bar.
Owens, Porter and Chloe Trautman then decided to approach Mauer about the situation. When asked how she knew Miller, Mauer responded that they had met through Instagram. She also confirmed that she and Miller had had sex in the past. Owens then accused Mauer of openly flirting with Miller. Mauer replied, “I mean, you should talk to him about that. He’s acting like you don’t even matter.” The confrontation escalated and Trautman even threw her drink on Mauer, who retaliated by shoving Trautman.
