'Teen Mom' Stars: "Wouldn't Change A Thing"

Fans have been watching the cast of Teen Mom deal with the trials and tribulations that come with having children young since 2009, and while these reality stars may have started as teen parents, we can't exactly call them that today. Teen Mom stars Amber Portwood, Tyler Baltierra, and Catelynn Lowell are now in their early 20s, and are facing entirely new challenges in their lives. Portwood served 17 months in prison on drug and domestic violence related charges, while Lowell and Baltierra are now parents to daughter Nova Reign after putting their first child, Carly, up for adoption in 2009. The former teen parents may have had plenty of challenges growing up, but at the MTV Movie Awards red carpet Portwood, Lowell, and Baltierra admitted that they wouldn't do anything differently.

"I think the more open and honest you are the more people connect with you and the more you're going to influence people or change them in a certain way," Lowell says of her experience filming the reality show. "I wouldn't change anything."

Portwood seconded the statement." I believe I am a stronger person because of everything I've been through."

All three parents aren't shy about sharing the experiences that made them stronger, even putting their struggles in writing. Portwood, who was joined on the red carpet by fiance Matt Baier, penned Never Too Late, a memoir about her struggles with addiction and overcoming obstacles. "It's a lot of encouragement, perseverance, and how it's never too late to change, no matter what you've been through, [or] where you've come from."

Lowell and Baltierra also put their journey down on paper in their own memoir, titled Conquering Chaos. "It really talks a lot about our past and our childhood and the reasons why we did things," says Lowell of their memoir.

Baltierra isn't worried about being judged for being honest with the world in the memoir, or on the reality show. "People will judge you if you're Mother Theresa, so people will judge you no matter what. Just be honest and real with your audience and see how they're reacting."

Baltierra is hoping that him and Lowell's adoption experience, which was chronicled on Teen Mom, may be able to help others: "We're working on an adoption documentary."

Lowell is also excited about a potential joint venture that may bring the Teen Moms stars together once again. "[Portwood and I] are thinking of getting together and hopefully doing a book tour soon."

"We don't get to see each other too much but every time we have an event we're always together," says Portwood of her Teen Mom co-stars. Baltierra agrees: "It's like we were hanging out yesterday."

So what's next for the Teen Mom stars? Portwood is going back to school: "I actually just started classes at college for behavioral science, so I'm getting my degree... I want to be known for changing the world and the view on addicts. "

As for Lowell, she's focused on parenting: "Raising my daughter. I'm a stay at home mom now."
