You probably don't need to strap Chrissy Teigen and John Legend [1] to a polygraph test to get the honest truth — just tweet at them, and they'll say what's on their minds. Regardless, Vanity Fair asked their December cover stars to take the plunge and interview each other for a lie detector test. The outlet released their funny video on Nov. 4 and it's just as ruthless as you might expect from a couple who love to troll each other [2].

With their spouse in the hot seat, Chrissy and John took the opportunity to ask the hard questions: "Have you ever cheated on me?" "Is our relationship just for publicity so you can get more Twitter followers?" "Would you ever have married me without a prenup?" "Do you get mad I wear robes so often?" Watch the full video above to see their hilarious answers, no holds barred. Hey, there's a reason why Luna and Miles's parents consider themselves "relationship goals" and we do too.
