Quite the opposite for me. The more I read about and see her, the more I like her and respect her.
She's embracing her feminine body. The red dress for 2024 People's Choice was great. As was the Oscar's dress. She explicitly sends a message that big boobs are cool with her statements about being glad she avoided a breast-reduction at 18. That could make a huge difference over the next decade if even a few women take away the message that their larger-than-c-cup boobs are an asset rather than a liability.
Body positivity has been taken so far that many in the mainstream seem to celebrate only bodies that are unhealthily obese, unhealthily rail-thin, or not biologically female. As silly as it seems, the message of body positivity for a conventionally attractive women is an outlier that parts of the chattering class are clearly struggling to process.
