The horny dudes of American Pie coined the term; Stacy's mom lived it. Pop culture crushes don't always have to be relegated to the talented performers who thrive onstage, especially if their parents can make you weak in the knees. Father's and Mother's Day come but once a year, which is why we're taking the time to recognize the beautiful men and women shepherding their talented children from behind the scenes. From Justin Bieber's MILF-y mom, to Mr. Malik's own interpretation of the Harry Styles swoop, enjoy our selection of the hottest moms, dads and maybe, just maybe, grandpas of our favorite pop stars. They're not all single, but you can dream. (And, after you're done reading, vote for your favorite pop-star parents right here!)
