Tiffany Haddish Reveals the Hilarious Piece of Dating Advice John Mayer Gave Her John Mayer has certainly had his fair share of celebrity hookups, Tiffany Haddish recently dished on the dating advice she received from Mayer during her interview with Stephen Colbert.  Haddish says that Mayer advised that she should tell interviewers that she’s “seeing” her celebrity crushes, which will prompt them to put up a picture of her and her crush side by side in their piece.  The “Kitchen” actress says that Mayer added that at that point her crush will see the interview and the idea of them dating would be implanted in their subconscious and it will attract the person she’s eyeing to her.  Do you agree with John Mayer’s advice?
