Christina Aguilera’s latest round of promo pics for her new album Bionic revealed a very interesting piece of jewelry  Betony Vernon’s “Petting” sex ring! Yes, the same $1,250 ring that Angelina Jolie wore for her June 2007 cover spread for Esquire!

The sex ring connects the index finger and thumb of the right hand and forms the chi murda position (the yoga/meditation gesture for a one-pointed, concentrated mind). A little naughty but still luxe!
