The 32-year-old rapper and "Ridiculousness" star today took a brief break from promoting Valentine's Day-released "I Want You" track to appear in something a little unexpected. The MTV face's 3.5 million Instagram followers got the star fronting fast-food chain Sonic, with it looking like West Coast was making a beeline for the milkshakes. She even included a pool splash in her videos. Check it out below.
