Lisa Rinna is definitely having a TMI moment.

The 49-year-old actress has a new gig -- promoting Depend adult diapers -- and modeled a pair underneath an evening gown, all in the name of charity, and Breaking Celebrity News has the video proof.

Lisa poured her rocking body into a skin tight black dress while wearing the diaper, Depend’s new Silhouette for Women, and explained why she’s promoting the brand.

“I am a champion for positive self image for women,” she said. “What I love about the new Silhouette is it makes a woman feel confident and it’s fashionable.”

The former Celebrity Apprentice contestant’s hunky husband Harry Hamlin weighed in on the subject. “She was poured into that dress,” he said. “You can’t even tell she’s wearing it.  I have to do the touch test, I can’t even feel it.”

Lisa is wearing the diapers for a good cause – in return for her endorsement Depend pledged to donate a whopping $250,000 to her fave charity Dress for Success!
