She found fame on MTV reality shows 16 & Pregnant and Teen Mom, which documented her pregnancy with now six-year-old daughter Sophia. Her child's tragically father passed away in a car crash ahead of her birth.
Since then, the 24-year-old has released an album and an autobiography. She also hit the headlines following the release of a sex tape and its sequel. "I would probably just say I am a top US reality TV star, a New York Times best-selling author, I dabble in adult toy lines as well and I have had a best-selling celebrity sex tape," she says.
Earlier this year, she hit the headlines after suffering an allergic reaction to anaesthetic while getting lip implants. Her lips swelled and she later said she felt lucky to be alive.
Why is she doing the show?
"For me it's because I can look at this as work and as a learning experience and I just love the opportunity."
What do her family think?
"My family really supports me and they are happy because since I became a Teen Mom I have always worked hard. I have never really been out of the country so I think they wanted me to take this time to do something more for me and look at it like a fun getaway."
Does she watch the show?
"I have caught bits and pieces. There's an entertainment reporter who has interviewed me and I have been at his parties - Perez Hilton. He was some other person. He doesn't act that outlandish in real life but he took it to some other place."
Does she have any bad habits?
"I live on my own and I do my own thing so I don't hear complaints much. I like to cook, I like to clean and be domestic."
Who did she want in the house?
"I really wish I could have Clint Eastwood in there with me. He is someone I grew up watching in movies and he is so iconic. Gotta love that voice!"
What does she want to get from the experience?
"I just want to get more of the British culture. I just embrace everything from language to ways of doing things and I think it's great that we have that in the House."
What would it mean to win?
"I would do a huge tour of Europe. That is pretty much what I am going to do regardless of whether I win or lose! I have been to Denmark and Sicily because that is where my family are, but I want to go to Milan, France, way down South."
