MTV has annouced Catelynn Lowell, Maci Bookout and Amber Portwood will return to Teen Mom in 2015, but their former co-star, Farrah Abraham, will not return.

The original Teen Mom cast first made their debut in 16 & Pregnant in 2009 and they continued to share their lives with viewers up until 2012.

Us Weekly, who first reported the news, notes how different their lives are at this stage.

Portwood was released from jail in November and is currently taking college classes. "I've changed so much that my focus and my goals are different than before,” she said. Her 5-year-old daughter, Leah, just started Kindergarten.

Meanwhile, Bookout will show her life with son Bentley, 5, and boyfriend of two years, Taylor McKinney. "My family and I are in such a new and interesting place in our lives," she told Us. "I feel like I have grown up so much since the last time that I filmed anything for TV, so it will be very interesting to show viewers how our lives have evolved."

Lowell and her fiancé, Tyler Baltierra, are now expecting their second child. They gave up their first baby, Carly, for adoption.

"I feel like documenting this pregnancy is totally different, because now it's our time to be parents," Lowell told Us.

There was no mention of Abraham, but it was highly speculated she wouldn't be returning after releasing a sex tape and launching a sex toy line.
