Being the most vocal member in a group called Naughty by Nature, it's no wonder Treach isn't shy about exposing himself. Last year he shot simulated sex scenes for an online adult movie, and for his role as a hit man in this spring's "Love and a Bullet" he shot a full-frontal nude scene.

But apparently baring all is limited to clothing. The man who built his star by being down with "O.P.P." and writing on ladies' kittens is a little more inhibited when it comes to the 411 on his personal relationships, especially the rumors that he has been dating Pink, who appears on Naughty by Nature's upcoming Iicons.

"That ain't nobody's business if we was or wasn't," said Treach, who went through a divorce with Pepa of Salt-n-Pepa last year. "I had a relationship in the past, and it was out there, everybody was in that. Nobody's getting in my life no more. The thing is, don't ask if I'm single or with somebody — ask me if I'm happy, then I know you're really concerned. Other than that, it's none of your business."

When the topic's strictly business, he's less tight-lipped.

"Pink, she's real cool," Treach said, beginning to explain how she came to guest star on "What You Wanna Do." "We met up at a party — it was all us, Lil' Kim, Junior M.A.F.I.A. Through that I was like, 'I really like your style.' She was like, 'I've been a fan of yours.' It was an exchange of numbers, and next thing we knew we did a song for [another] project that's coming out and we did it for our album."

On "What You Wanna Do," Pink sings about being driven crazy by the group's naughty style.

"The hook was already there. She came in, added her flavor, her riffs and turned it around," Treach said. "It's a smoker."

"Pink is really talented," Treach's partner Vinnie added. "She got in there, she knew what to do — how to construct and add on and stack. She heard certain things and changed certain pitches. She didn't need no vocal coach."

The guys said they didn't have to coach 3LW, either, for their cameo on Iicons' first single, "Feels Good," because it was a long-distance team effort.

"We had to stream it [via satellite]," Vinnie said. "They were out in L.A., and we were in New York. Everything is about overhead, to make it cost-efficient, and for the timing that was the best way to do it."

"We would rather be in the studio with the artists," Treach said. "That was the first time we worked with that system, but it [came out good] because we built the song together. We were talking to each other right there. It wasn't like we weren't creatively there together."

"Feels Good," can be heard on the radio now and on Naughty's new LP, which is due April 23, according to their spokesperson.
