Alex Mariah Peter (28) showed her physical transformation on Instagram. The 28-year-old, who won the casting show "Germany's next Topmodel" in 2021, posted a before-and-after picture. The first photo is from the premiere celebration of the second season of the Netflix series "Kaulitz & Kaulitz" in June 2025, where she listed her weight as 261.7 pounds. In the photo, she is wearing light-colored, short glitter shorts and a pink tank top.
The photo she placed next to it is from the premiere of the third season of the series, which took place a few days ago. She presented a black mini dress at the event. Here too, Alex Mariah Peter added her weight: 200.4 lbs.
Alex Mariah Peter is proud of herself
She also placed additional snapshots of herself from both premieres side by side and pointed out how her own satisfaction, body language, and self-confidence have changed. In the text she shared with it, she writes: "K&K2 Premiere vs. K&K3. I'd be lying if I said I wasn't proud."
Alex Mariah Peter added in her post: "Just a single year." And further: "Still with ups & downs", but at the end of the day, she remained consistent. "I can't believe how obvious my emotional state was to see, probably to everyone except me."
