Just watched her new video. That is definitely not her in the frame. Here are the only logical options:
1. "Digital Replacement" (40%)
She is getting older, and her brand requires eternal youth. She built an AI-generated version of herself to slowly replace her on camera. The "debut" is a live test run. The weird mark on her cheek is a rendering glitch they missed or did not bother fixing.
2. "VFX Troll / Meta-joke" (35%)
She is a VFX specialist. This is just a parody: "I am too compromised to debut for real, so here is my AI debut." Self-irony. The cheek mark was left intentionally as an easter egg, a signal to the audience that this is not real.
3. "Botched Surgery" (15%)
The long silence was not about AI, it was real plastic surgery. Her face looks completely different because of post-op swelling. The "mark" is a laser scar, bruise, or pigmentation poorly covered with makeup.
4. "Unauthorized Access / Altered Video" (10%)
Someone else made an altered version of her face, slapped a fake M Countdown watermark on it, and uploaded it. Either her account got accessed by a third party or someone is just using her likeness.
Conclusion:
It is 100% not her. The only question is whether she made this edit herself (1 or 2) to transition into a digital model, or if it is outside interference (3 or 4). That cheek mark is the main clue, it is either a mistake or a deliberate message.
