"I acted inappropriately toward Ms. Burton and I sincerely apologize," the 45-year-old actor tweeted in reference to his 2003 appearance on the show.
The apology comes following Ben's scathing comments about his one time pal Harvey Weinstein's multiple sexual incidents with budding actresses, spanning over several decades.
Irate fans took to social media, calling Ben a hypocrite, citing his own behavior on MTV.
Footage resurfaced, showing an uncomfortable encounter between him and then Hilarie who was 18 at the time. The actress, seen here with husband Jeffrey Dean Morgan, is now one of the stars of Fox's Lethal Weapon.
"I remember when that happened and never forgot about it. We see you," Hilarie tweeted.
