"Not Ur GF" is the first single from Bond and Riley since 2015's "Summer", which also featured Avelino and Dun D.
The two collaborators have previously released two projects together - 2013's Meds and 2012's Emergency Room.
"Not Ur GF" is the first single to be released on Riley's Loup Ent imprint, and marks the first release from Bond since dropping her He's Not Mine album last year.
