Cardi B Says She's a 'Prisoner of Fame' in Emotional Video After Met Gala Party

Cardi B has had it with fame, saying the price of being a celebrity has created constant ridicule and has put a target on her back ... after some drama from her Met Gala party.

Cardi took to IG Live Tuesday and let it all out -- saying she feels like a prisoner of fame -- and that she hasn't been able to be her true self since 2014. The timing of her video comes on the heels of some now-viral clips popping up from her Met Gala after-party.

In one clip, Cardi offers a toast to partygoers at Playboy's The Boom Boom After Party, wishing them a good time and encouraging them to drink up ... but it's her snorting gesture that has people pissed.

Cardi seemingly addressed that anger in her live confessional, saying she feels like she can't even make jokes anymore without people taking it seriously.

There's also a clip of Billie Eilish at the bash, who many thought was calling Cardi "weird" as she entertained guests. Cardi squashed that rumor too, posting DMs between her and Eilish where Billie says she was only calling the partygoers taking photos of Cardi's butt "weird" ... so no beef there.
