Get ready to "Take It Off," because things are heating up (again). We're taking it back to 2010, when Katy Perry [1] sizzled screens as a bare "California Gurl" in Candy Land, Usher [2] was making us yell "OMG" with his dance moves, Eminem [3] would just "Love the Way You Lie," and Lady Gaga [4] was breaking things off with "Alejandro."

Read on to see some of our favourite sexy music videos from good old 2010.
