I generally agree, but other than her turning around to show her ass, I don't see what she did wrong, and that's a mainstream pose for entertainers now. I recall years ago being struck that what I consider "club poses" were making it on to the red carpet. She got close but for the most part there was daylight between her pelvis and his, until he turned a bit and put his hip out there. I think she was mostly caught up as a fangirl. She was even fanning herself and giggling with her girls like she couldn't believe it was happening.
As far as his setting the standard and example for his family: he DID. HE posted videos of her in the past. Nothing that she did, clothing or even movement wise in showing her ass, violated past precedent that HE set. I didn't know about the shirtless video, but like the guy said, it was usher who set him off, not the outfit.
A lot of people are commenting that she threw her relationship away over Usher, mentioned his herpes etc like she slept with him or something. Also comments about how NOW shes going to be a single mother (Newsflash: he didn't put a ring on it, she's ALREADY a single mother.) The menfolk here who go to strip clubs etc expect their women to be ok with it and say it shouldn't matter where they get their appetite, as long as they eat at home. Why doesn't that apply with her?
