First of all, 99 out of 100 times an actress or model get accused of a reduction, it's from guys who haven't been around a woman for any length of time. Boobs shrink naturally all the time for a ton of different reasons.
No, Leni Klum didn't get a reduction you silly muppets.
But if this video is unfiltered, she definitely fucked up her face. Fuck plastic surgery.
