Oh Miley Cyrus, what shenanigans are you up to now?

The 20-year-old star was spotted last night in L.A. hanging out with an unlikely companion… a blow-up sex doll!

The former Disney star, turned wild child posted a photo on Twitter last night, showing off her new friend.

The photo was posted with the caption, “Does this count for the carpool lane? Such a nice Xmas gift.”

Well it’s good to know the doll was securely fastened with a seat belt. I guess she’s not such an airhead after all… (Sorry I had to).

Oh Miley, you know how to celebrate the Holidays right!
