Supermodel Cindy Crawford proved she's still a super babe. The 49-year-old mom of two posted a sexy topless photo of herself in honor of the Instagram trend Throwback Thursday and her family's rustic summer vacation, E! News reported.

The racy black-and-white photo was taken in 2013 during a menswear photo shoot for V magazine, according to the Daily Mail. In it, Crawford posed topless, wearing nothing but a pair of dark baggy jeans cuffed at the ankle and a wristwatch. Her left side was facing the camera as she held her body pressed against a tree. She posed with a sultry expression on her face, all while exposing an ample amount of side boob.

"#TBT tree hugger," she captioned the seductive shot, "a little inspiration for our woodsy summer holiday." She tagged the photographer Sebastian Faena in the post as well.

Crawford is currently on a family vacation with her hubby Rande Gerber and the couple's beautiful model-esque children, 13-year-old Kaia and 16-year-old Presley. She's been documenting their summer holiday with gorgeous photos of her family at what appears to be the Gerber Point Lodge in Canada, according to Us Weekly. Photos of her children have gorgeous lake and mountain views as the backdrop and one interior shot shows Gerber sitting in front of a large, rustic fire place.
