The latest addition is hip-hop superstar Nicki Minaj, who will star in her own mobile game in the summer of 2016.
The exclusive agreement covers Minaj's name, likeness, voice, and creative direction to develop what Glu is calling a "one-of-a-kind digital experience".
Significantly, Glu also highlighted the performer's social reach, which is 42 million on Facebook, 30 million on Instagram, 20 million on Twitter, and 9.1 million on Vevo.
Indeed, Glu was also keen to point out that its "celebrity gaming platform" now has around 650 million followers across all social media channels.
