'The Host's Leaderboard': Tom Bergeron on his new haircut, throwing to Diane Sawyer, and Mark Ballas' 'misconstrued' Monday night hand gesture

My Week 7 chat with Dancing With the Stars host Tom Bergeron is chock full o’ gems:

On his hair: “I don’t mind if it’s graying, as long as it’s staying.”

Tom and the DWTS production staff have nothing better to do than stand around and talk about the brilliance of EW.com’s Hidden Gems. How awful!

When throwing to Diane Sawyer — with whom he has a strictly flirtatious professional relationship thanks to a Good Morning America stint — Tom had to make a conscious effort to tone down the jauntiness and “maintain a certain level of ballroom gravitas.”

Tom believes Mark Ballas’s explanation of Monday’s “wanker” hand gesture: It was intended for his dad, Corky, as a “You gotta roll the dice with the choreography” inside joke. But as Tom counseled Mark after the show, “If that was a gesture of self-gratification, you’re really bragging about your size, because that was WAY off to the side.”

Press the “play” triangle to hear my imaginary friend in all his alternate-universe glory!
