TMI, thy name is Fergie. The alicious-prone singer is revealing a mite too much information as she makes the rounds to promote her brief appearance in "Grindhouse," oversharing details of both past and present passionate exploits.

"I have had lesbian experiences in the past," says Fergie (via In Touch), 32, who just happens to play a lesbian in the flick. "I am a very sexual person."

Thankfully, that sexuality is something Josh Duhamel, 34, her easy-on-the-eyes boyfriend of two-plus years, not only appears to appreciate, but also encourages.

In the May issue of Playboy (via People), Fergie fesses up that he "dances for me in private, in some very interesting outfits," before descriptively adding that he "bought me these amazing boots at the Hustler store. They're thigh-high patent leather with a big long zipper. They're hard to get on, but it's worth it."

We'll give you a second to digest the image of Josh shaking his groove thing as Fergie watches while encased in shiny, binding footwear. Done with the brain bleaching? OK, moving on ...

The Black Eyes Peas belter adds that the actor's private dancer moments are often accompanied by her music, which she says he cues up with nary a nudge from her.

"Make him? He wants to," insists Fergie, who doesn't detail whether he prefers her more highbrow offerings such as "My Humps," or the lyrical subtlety of, say, a "London Bridge."

"He likes dancing. I slow dance with him, but I have to stand on his feet because I'm too short," she explains. "He's 6'3" and I'm 5'4". Luckily I took ballet, so I know how to stand en pointe."

Fergie also comes clean about that much-discussed 2005 photo that shows her performing with a suspiciously large stain on her pants, admitting she was a wee bit mortified over the leaked pic.

"Embarrassment," concedes Fergie, who has previously said she forgot to hit the bathroom in between quaffing some champagne and hopping on stage. "Everyone told me not to talk about it, but I wanted to call people and tell them what had happened. I was advised not to, and I didn't for a while. Now I'm just honest about it. It's embarrassing, but you just have to let it go at some point."
