It's been a few years since we last saw her, but Taylor Swift's hip-hop alter-ego T-Swizzle made a cameo during last night's Grammy nominations festivities. The country-pop star broke into a bit of reluctant beat-boxing at the behest of co-host LL Cool J, who promised Swift, "I can't sing, so we're even." Much to the delight of everyone, Cool James proceeded to serenade the crowd with a rendition of "Mean" over Swift's fetchingly straightforward beat. Eat your heart out, Internet.
