I'm not surprised these two are kindred spirits. Kim Kardashian, who, yes, I kind of love, attended the launch party of Heatherette's new make-up line at M.A.C Pro North Robertson in L.A. yesterday ... and apparently demoed some new product on designer Richie Rich himself! Who's having more fun here?

Kim has modeled for Heatherette in the past - so has Paris Hilton, Mya and Jenna Jameson, among many others - and it looks like the designers' work still gets her going. Keep it together, Kim!

More gayness after the jump!

Heatherette ... Fashionable!

"TV personality" Brittny Gastineau got her little butt flanked by nearly-nude Heatherette models. Lucky girl.

Say hello the boys, Brit!

And Nikki Sixx and Kat Von D were at the event as well ... Yikes! Who's channeling "Toxic" Britney?

Busy girl: Kim scooted over to the Details magazine Mavericks 2008 issue cocktail party in Bev Hills

Enjoy it while you can! Ryan Seacrest was on the cover of the Mavericks issue.

Hmm. Not too happy...? I thought you guys loved Ryan.
