Ty Dolla $ign’s mixtape Sign Language drops today. This project featuring the single "Lord Knows" is one of 11 cuts from the project. The singer-songwriter is still working on his debut album as well as few collaborating projects, including one with Rich Homie Quan and another with YG and DJ Mustard. But that’s not all. The XXL Freshman claims that he also has music in the works with Rihanna. Ty told Damon Campbell on The Damon Campbell Show that Drake introduced her to his music back in 2012 when she was working on Unapologetic.

“I did a song with Rihanna recently and I was like ‘how did you find out about me or whatever?’ And she said ‘Drake.’” The singer was a big fan of Ty’s song “Work” and asked for him to do something similar for her upcoming project.
