Karlie Redd got exposed last night on Love & Hiphop - for having a threesome with fellow castmate Pooh Hicks (Hiriam Hicks’ wife) and her husband.

Karli is currently engaged to an Atlanta hustler named Arkansas Mo. She's trying to re-make her image, and put her past behind her. But last night Pooh brought up Karli's scandalous past - on the VH1 hit show.

The drama popped off when Pooh showed up at Karlie’s store to ask why she wasn’t invited to Karli's engagement party. Karlie told her old friend that she stopped being Pooh’s friend because Pooh was a "clout chaser." Karli further told her that she has moved on from the types of things they used to do for fun.

The discussion quickly descended into an argument.

While the two were arguing, Pooh reminded Karli that she used to have threesomes with Pooh and her husband music mogul Hiriam Hicks. For those that don't know, Hiriam is the man who helped make the careers of New Edition, Dru Hill, and Bell Biv Devoe.

Hiriam and Pooh are swingers, who frequently bring other women into their bed. And they claim that Karli used to be one of them.

Last night, Pooh yelled at Karli, "You s*cked Hiriam's d*ck, and you used to have your tongue in my a**."

Here's the video of Karli being exposed:

In 2001, Redd was cast in the movie Black Spring Break 2 where she was credited as Keisha "Karlie" Lewis. In 2008, Redd was in the VH1 reality show Scream Queens. In 2012 she was cast in the spin-off VH1 reality show, Love & Hip Hop: Atlanta. Redd has dated hip hop artists Benzino and Yung Joc on the show. According to an analysis done by a language analytics company, Redd's appearances on the fifth season of the show garnered 16% of all emotional reactions about the show collected from social media data, with the largest share of them being negative.
