The star was with husband Jay Z in Sin City for the Cotto versus Alvarez fight and sat ring side in a plunging black dress.
Dr. Anthony Youn, who has never treated the multi-award winning star, 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.
He said: "It appears that she's had a rhinoplasty, causing her nose to look noticeably thinner and refined.

"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.
She even appeared to be anti those procedures in her 2013 video for single Pretty Hurts.

Playing a woman getting a face lift and botox, Beyonce said she wanted to highlight the pressures on women in society.
"I'm pretending to get a facelift and Botox," she said in a behind-the-scenes video posted to Instagram.
"It represents all the things that people go through to put up with the pressure that society puts on us."
