The MTV stars from both Teen Mom and Teen Mom 2 got together this weekend for their reunion show but one of its biggest names – Amber Portwood -- was noticeably absent.

The troubled young mother was released from a Madison County, Indiana correctional facility February 24th but is still under strict probation supervision and is fitted with an ankle-monitoring tracking device.

There is nothing better than a good old scandal and that made 2011 a banner year for reality TV!

From cheating spouses, to fake marriages to shocking suicides and risking children’s lives, reality stars showed their true colors by fighting, making-up, dodging debt and raking up arrests, and RadarOnline.com has a gallery of the biggest scandals of the year.

Kim Kardashian tied the knot with Kris Humphries in an $18 million made-for-TV extravaganza but filed for divorce just 72 days later, prompting outcry that the nuptials were fake and only for ratings on her reality show. The backlash was swift, especially when Kim cashed in with huge ratings for the new season of Kourtney and Kim Take New York, which was re-edited to make Kris look like the bad guy.

Taylor Armstrong’s financial troubles were simmering when her estranged husband Russell hanged himself in August, followed by the shocking news that Russell had allegedly abused her during their tumultuous marriage.  His suicide stunned family and friends, but the couple’s troubles are proving to be a ratings bonanza for the Real Housewives of Beverly Hills, with their counseling sessions aired on TV and the couple’s dark secrets revealed weekly.

Leah Messer has filed for divorce from Corey Simms, her husband of just six months. The Teen Mom 2 star filed in Kanawha County, West Virginia on Friday.

The next day, with the MTV cameras rolling, the teen cried over the legal docs as she sat with a close friend, in a park near the county courthouse.

The split was included in a lengthy list of divorce filings reported in Saturday's Charleston Gazette-Mail.  "Leah Messer Simms from Corey Simms," it simply said.

But there is nothing simple or uncomplicated about this uncoupling. Leah and Corey, who wed October 17 in Charleston, are parents to 16-month-old twins Aleeah and Aliannah.  Ali was was born with several disabilities, and her young parents discussed the challenges they faced with her in a episode of their show.

Leah, 18, and Corey's wedding was shown in the Teen Mom 2 season finale.  And during the reality show's recently aired reunion special, Leah spoke about the relationship.  "Marriage to me is a big commitment.  If I took that vow it is going to be forever," she said.

But "forever" has already come and gone, and with cameras rolling right from the time of the divorce filing, Leah and Corey's bust-up is being set up as one of the major story.
