Didn't you know? It's expensive to be Erika Jayne, darling.

The dance diva makes her grand return on "XXPEN$IVE," a throbbing slice of neon-bathed electro pop co-written by Ferras (Adam Lambert), Jesse Saint John (Britney Spears) and Sarah Hudson (Katy Perry)—and much like John Hammond, she's spared no expense.

Jayne unleashes her inner sex kitten in the titillating, colorful video for the audacious dance floor banger, as she writhes in pastel lingerie, indulges in a bubble bath—while wearing a crystal corset, no less—and gets her '80s Jane Fonda on in a bright pink leotard. (That split would make Barbie's head spin!)

"It's expensive to be me, eh eh eh eh eh / Lookin' this good don't come for free, eh eh eh," the Real Housewives of Beverly Hills queen (sorry Vanderpump, you've been dethroned) proclaims on the gaudy-lux track's sassy hook. And no, she "still don't give a f---."

Watch above.
