Aubrey O’Day has pulled a page from the Book of Allen, Lohan & Rihanna and frenched-up her finger with a funky new tattoo.

“friday jones did my new tat at her launch party!” the former Danity Kane star wrote in a Tweet Tuesday:

Aubrey’s tiny tattoo reads “je ne sais quois,” which is French for “I know not what.”

Huh?

Aubrey O’Day will replace former Spice Girl Mel B in the Las Vegas burlesque production Peepshow this September. She joins fellow former Playboy centerfold Holly Madison, who also appears in the show.
