Nicki Minaj fans worldwide are asking “#GiuseppeWhatsGood?” in support of the rapper’s Twitter rant about designer Giuseppe Zanotti allegedly using her name for a recent sneaker collection without her permission. (“What’s good?” is a reference to Minaj’s onstage showdown with Miley Cyrus at the 2015 VMAs, which spawned countless memes and even some commemorative merchandise.)

The newest version of the “Nicki” sneaker retails for $675 and comes in several color options, including a “pink python-printed leather” — one of Minaj’s signatures.

Zanotti has released collaborations with other artists including Jennifer Lopez and Zayn Malik, but allegedly has denied Minaj’s request to team up on a collection. “Recently when he gave other artists capsule collections, my agency reached out and was told they’re not taking our call,” tweeted Minaj.

Minaj is asking that Zanotti donate proceeds from sales of the “Nicki” sneakers to St. Jude Children’s Research Hospital, adding that she will match the donations up to $500,000.
