Teen Mom 3's Katie Yeager is smart and gorgeous, an envy-worthy combination. Nowadays, she's all grown up with a bouncing baby girl, a full-time job, and a college degree on the horizon, but prior to her early introduction to adulthood, she was just your average American gal. Check out this senior picture of Katie looking gorgeous and fresh-faced before baby Molli came along.

"#throwbackthrusday Senior photos," she captioned the picture, which was most likely taken in the fall of 2010 (considering she graduated in 2011).  

Apparently, the setting for Katie's senior portraits have special significance. The now-20-year-old starlet explains that the bench was used for a sex scene in the 1998 movie SLC Punk!, which took place in Salt Lake City where Katie grew up.

"Little does my mother know this in the bench that they had sex on in the movie SLC punk. Shhhhhh!" Katie adds.

Our lips are sealed, but we may have to add SLC Punk! to our Netflix queue. It's been a while —  we were in middle school when that movie came out. Shhhhhh!
