If you can't help but sing along and dance to Biz Markie's "Just a Friend," you're in hot company. The man behind the catchy hit made a surprise appearance at Comic-Con in San Diego on Friday, joining Channing Tatum  and the Book of Life cast on stage. Channing threw his hands up when Biz started performing the song, which is featured in the upcoming animated movie. Eventually, Biz made his way over to Channing, who belted out the hook with a laugh. Watch the video above to see Channing's cute moment, and then check out all the stars we've seen at Comic-Con  so far!
