It hasn't even been 24 hours since Teen Mom premiered on Aug. 26, and reality star Katie Yeager is already fighting a nude photo scandal.

According to reports, an ex-boyfriend of Yeager claimed she sent him the explicit pictures. 

"The photos were sexted to me... she loved to send messages, all the time," the owner of the racy images  told Radar Online.

The images allegedly only seen by the celebrity site reportedly displays the 19-year-old MTV star in various positions, including posing naked in front of a mirror, playing with a sex toy, pleasuring herself and lying nude on a bed.

Yeager previously said she wanted to change the face of Teen Mom.

"When I started researching [Teen Mom] I said, 'wow! It really is making a difference," she said. "It's controversial, but it's definitely helping young girls to see the consequences of having unprotected sex and having sex too early, and I felt like I want to help."

She added that negative people will always try to tear her down.

"There's always going to be negative people out there, even if you're not on a TV show. I've accepted that. There are people who agree with my life, the way my life is, or just don't like me for whatever reason. I have enough support on my end in the people that are around me in my life. That's the only thing that matters to me," she revealed. 

As for the nude pics, Yeager isn't the only Teen Mom who has exposed herself. Amber Portwood posed for a series of photos, while Jenelle Evans did a topless shoot. 

Earlier this year, Farrah Abraham released her own sex tape/porn film Farrah Superstar Backdoor Teen Mom.
