Jennifer Lopez is gearing up to guest star as a man taming no-nonsense self-help author by the name of Anita Appleby on “How I Met Your Mother.”

On the show, she teaches women how to retrain men through the power of denial. Her episode is slated to air in March, according to network sources.

In this arc, Robin tells Anita (Lopez) of Barney’s womanizing ways and Anita is set out to break him.

Executive producer and co-creator Carter Bays said, “We’re looking forward to a week of revealing outfits and sexy dance moves the likes of which this show hasn’t seen since Regis Philbin guest starred.”
