Beyonce was with her husband Jay Z in Vegas for the Cotto versus Alvarez fight, and sat ring-side in a plunging black dress.
This new accusation comes after Britney Spears ex-husband, Kevin Federline called her out on Twitter for having botox.
So sad when a beautiful woman chops and screws her face up w/Botox and surgery... #sawface— Kevin Federline (@kevinfederline) November 22, 2015
Dr. Anthony Youn, told Radar Online that it appeared the singer - who has never confirmed any kind of surgery - appeared to show signs of having botox, a rhinoplasty and lip filers.
"Her upper lip also looks like it may have been moderately enhanced, possibly with a filler like Juvederm," he continued.
"Her smile lines, aka the nasolabial folds, also appear to have been reduced, maybe with an injectable filler like Restylane."
Beyonce has always maintained that she's never had surgery. Just last month, she was accused of lightening her skin by a singer, Mica Paris.
I think it's on days like this Beyonce wears "my favourite shirt."
Yes, Can I live? LOL!
