Selena Gomez looked hotter than ever on the Victoria's Secret runway during Tuesday night's broadcast of their annual fashion show and while she was singing her heart out, several haters had some not-so-nice words to say about her singing.

During the show, the 23-year-old performed "Hands To Myself" and "Me & My Girls" in a sexy, and extremely low-cut, black dress while the models walked the runway for the ultimate girl power moment and some viewers weren't buying the singer's vocal talent. Several people began accusing Gomez of lip syncing during the show and Gomez wasn't having it, according to E! News. So, she reached out to these haters in the best and most subtle way possible: with an Instagram comment.

"Yes I f--king sing live," she commented on Victoria's Secret's photo of her performing.

These viewers apparently don't know what they're talking about, though, because she sounded incredible, but the best part of her performance - and possible the entire show - was when Gomez slapped Gigi Hadid's butt as she passed by. The two are really good friends, so we knew there would be some sort of interaction when Hadid walked by, but the butt slap was totally unexpected, and adorable.

Watch the interaction in the video below.
