Months after the acclaimed film Precious hit movie theaters, people are still buzzing about featured star Mariah Carey's shockingly unglamorous look -- including Mariah Carey.

At the tip of everyone's lips? The singer-turned-actress' mustache as Mrs. Weiss, a drab, 1980s-era social worker. Precious' makeup artist Toy R. Van Lierop told Us in November that she did not use any cosmetics to create a fake 'stache for Carey; at the time, the star's rep denied claims that the facial hair was real.

In a new interview with Newsweek, Carey once again flirts with the hairy truth.

"Did you not see the redness under my eyes, nose--and the mustache? That's the only thing I care about," Carey, 39, says.

"I lost all the vanity stuff, but when people really started analyzing, they have to ask about the mustache," she explains. "Why is it important? Oh, my goodness, it's hideous."

The usually dolled-up Grammy winner adds, "That's not my no-makeup look--just FYI. Could you let [Newsweek] readers know?...I don't think Nick [Cannon, her husband] would be here if that was my look."

In September, Carey told Us of the gritty role, "I knew they wanted me to be as homely as possible..So I was like, That's cool."

Currently enjoying raves for her Precious performance, Carey admits that her acting debut in 2001's Glitter was less successful.

"I always have wanted to act," she explains, "But maybe I needed that much of a fall to get where I needed to go...That period of time was just a mess."

Carey famously suffered a "breakdown" in 2001 following the disastrous release of Glitter and an accompanying album. "I'm not blaming anyone, but the [Glitter] script wasn't even done when we started that movie, and it was all over the place."
