Officially, all CBS and The Recording Academy have confirmed is that pop icon Madonna will perform at Sunday’s 56th Annual Grammy Awards ceremony.

If a gossip outlet’s report is true, however, the nature of her performance is now clear

According to Us Weekly, Madonna will join Best New Artist, Album of the Year and Song of the Year nominees Macklemore & Ryan Lewis for a rendition of their “Same Love.”

It is unclear if Madonna will sing in the stead of–or in addition to–Mary Lambert, who sings the chorus on the record.
