Can we talk about Lady Gaga's nails? Okay, maybe later.

Perhaps you've heard: Lady Gaga launched Fame, her black eau de parfum, at Macy's Herald Square in New York City on September 14th. The night before, she hosted a lavish masquerade party (it included an on-site tattoo session) at the Guggenheim Museum that evening. Here, check out the event photos (Gaga's shoes! Nails! Lindsay Lohan! Stam!) and Gaga interview videos:

Yup. She's dressed as the Fame bottle.

I bet Gaga would say these are super-comfy shoes. Yes? No?

I like Gaga's lipstick colour.

In an interview on an Australian radio show, Gaga gave a unique description of her fragrance....

I like Gaga's dress. A lot.

Dig the hair accessory.

Gaga's Fame manicure. Whoa, those nails.

Gaga's tat from the night before (you'll see it happen in the third video, at the bottom of this post).

The evening before, at the Guggenheim Museum, Gaga's shindig guest list included designers, models and famous peeps  such as Marc Jacobs, Alexander Wang, Jason Wu, Jessica Stam, Yoko Ono, Lindsay Lohan (below) and Paris Hilton.

A giant version of the Fame bottle was part of "Sleeping With Gaga," a performance art piece in which Lady Gaga emerged from the bottle for "15 Minutes of Fame," followed by a return to the interior for an on-site tattoo by Mark Mahoney, a tattoo artist of considerable reknown.

Photographer and director Steven Klein was a fête guest, too -- below is the film he made with Gaga for Fame.

Here's an interview with Lady Gaga about the fragrance details: "It's my perfume expression of fame, it's not my personal expression of it. I'm not saying anything in the fragrance about my personal life. I'm just making a funny product," she says.

More interviews, this time with party attendees, such as Steven Klein, Marc Jacobs, Yoko Ono and more -- plus red-carpet posing lessons from Paris Hilton and Gaga's on-site (in-bottle) tattoo. Say, which of these guests would you want at a party at your house?

And here's how the Macy's Herald Square launch unfolded:

Oh hey -- what do you think of the fragrance?
