Cardi B returned to Instagram on Wednesday to promote her upcoming single with former collaborator, Bruno Mars.

The "Money" rapper deactivated her account earlier in the week after facing some backlash for her Grammy win in the Best Rap Album category. Ariana Grande tweeted "this is bullsh*t" after Cardi took home the award, but who can doubt that Cardi is one of the hardest working artists in the game right now? And one of the best performers?

"Ok so I’m back from retirement to announce I have a brand new song coming out Friday at midnight with @brunomars . # twogrammywinningartist 🏆🏆," Cardi wrote. 

Cardi previously collaborated on the remix to his 24K Magic track "Finesse," and the two were scheduled to go on tour together before Cardi announced her pregnancy to the world.

Several celebrities have spoken out in defense of Cardi's win including Fabolous, Chance The Rapper, Lady Gaga, Nipsey Hussle, Remy Ma, Lil Kim, Plies and J. Cole.
