Lady Gaga Welcomes the New Year, Butt First

Lady Gaga's getting deep for 2018, but not so deep to be above an awesome thong bikini photo.

Gaga struck this pose somewhere in the wilds of ... well, we don't know, and who really cares? She looks amazing, and sounds like her New Year celebration was totally serene, and exactly the way she wanted it.

Her caption on the pic -- "Happy New Year. To happiness. Health. Love. And to the simplicity of beautiful unforgettable nature, life."

Thongs for dropping some philosophy on us, Gaga.
