When Nina Dobrev went topless to support ObamaCare earlier this month, it marked the most skin she’d shown on social media, but on October 24, she set a new record with sexy bathtime photos.

To celebrate Throwback Thursday, Nina posted some near-naked pics of her as Katherine Piece on The Vampire Diaries, showing off her gorgeous toned legs while surrounded by suds in the tub.

The bubbles are perfectly placed, covering up anything she doesn’t want on camera, in one photo as she looks down, one leg hoisted up on the side of the tub. She looks serious and serene between takes in this one, but in the next photo she posted, it’s the exact opposite.

In a second photo, Nina is giggling while the crew makes bubbles for her in the tub! Must be weird with people staring at her naked in the bath, but it’s all in a day’s work for the vampy actress.

“#TVDTBT BehindTheScenes-Making Bubbles!! All day on set in a hot bath. Tough day at work! :P It was all fun+games til I became a human prune,” Nina captioned the silly pic. Unfortunately, she did not show off her pruney fingers, but we’ll let it slide.

What do you think of Nina’s sexy, sudsy photos? Sound off below!
