Madonna paid tribute to her friend and collaborator Prince to close out tonight’s Billboard Music Awards. Questlove introduced the singer, who made her entrance on a huge purple throne and proceeded to perform a somber rendition of “Nothing Compares 2 U.” Stevie Wonder then joined her on stage to sing “Purple Rain.” Watch the performance below.

UPDATE: As expected there were plenty of gripes on social media about the performance, including this shady tweet from BET (who will stage a Prince tribute at their awards next month)…

Questlove has chimed in to defend the Madonna performance and these tributes in general.

because of P’s well known love for the *poof* vanishing act. A lot of us are left feeling incomplete in the act of saying goodbye.

For starters it’s hard to accept him no longer being here. & in the upcoming award season for ’17 there will be a gang of tributes

Naturally there will be folded arms & shade thrown because the Purple Standard is hard boots to fill & a lot of us don’t wanna come 2 grips

—w the fact that Prince–(an on the surface) face of health & invincible agelessness subcomb to something so….friggin basic

So w mourning will come sadness & anger. 1st week I cried. 2nd week I tried to atone for his sins w gettin 8-10 hrs of sleep he didn’t get

— Questlove Gomez (@questlove) May 23, 2016

Now anger is in the air w who (in our eyes) is allowed to mourn & how they are allowed to mourn.—none of us were prepared for his death

— Questlove Gomez (@questlove) May 23, 2016

So I know there is gonna be ALOT of “feel a certain ways” about who you want to see do his music justice—but you gotta put that aside yall

Every Prince rendition will not be a life changing orgasmic xperience. Just to SING his work is brave enough. Again feeling are on high

— Questlove Gomez (@questlove) May 23, 2016

And EVERYBODY wants and deserves a chance to say goodbye in their own way. But remember: there will be AMAs, SoulTrain, NAACP, mtv, GRAMMYS

— Questlove Gomez (@questlove) May 23, 2016

And a gazillion other tributes. But the point is let’s not get ugly w playing the “Prince would and wouldn’t approve” game.

— Questlove Gomez (@questlove) May 23, 2016

….& this isn’t *just about* the Madge/Stevie tribute btw

— Questlove Gomez (@questlove) May 23, 2016

I’ve been gettin earfuls from in/outside the Purple Circle concerning inclu/exclusions of his estate/work/memorials/tributes who in who not.

UPDATE 2: Madonna responds to the criticism.

Anyone who wants to do a tribute to Prince is welcome to. Whatever your age Gender or skin Color. If you loved him and he inspired you then show it!!!! I love Prince 4 ever 💜☔️👑🙏🏻 @beautyandessexlv
