'Teen Mom 2' star Leah Messer-Calvert heads to rehab, while Chelsea and boyfriend get a pet pig, and Nathan Griffith moves out

(MTV)

Drama seems to follow "Teen Mom 2" stars and the latest buzz is that Leah Messer-Calvert has entered rehab for a month, while Nathan Griffith has moved out of Jenelle Evans' home.

InTouch Weekly reports that Leah has checked into a rehabilitation facility for a period of thirty days to overcome her alleged addiction to painkillers. She has agreed to enter the West Virginia-based facility on the condition that her three daughters would visit her. Messer has two 5-year-old twin daughters, Aliannah and Aleeah, from ex-husband Corey Simms, and another 2-year-old daughter named Adalynn from estranged husband Jeremy Calvert.

A source has cited that Leah isn't ready to come clean about her alleged addiction problems and has told friends that she is seeking therapy. "She's still telling people she's going away for therapy. They're hoping her denial doesn't stop her from making a fresh start", said the source.

Reports of Leah's alleged drug problems have been doing the rounds ever since an episode of the MTV reality show saw her nodding off while she was on medication. Starcasm reports that Messer allegedly spends $1,000 a week on pills and cannot go without opiates even for a single day. However, the 23-year-old has always given the impression that she is focused on being fit and has never acknowledged her rehab stint, or her reported addiction issues on Twitter.

Meanwhile, OK! Magazine reports that Nathan Griffith has moved out of Jenelle Evans' home, confirming rumors that the couple have split. Evans is ready to date, but wants to take things slowly and has raised her standards for men. She is concentrating on graduating from medical assisting school and penning a memoir.

Another OK! Magazine report cites that Chelsea Houska and boyfriend Cole DeBoer have expanded their family by welcoming a pet pig named Pete. The fact that they have a pet has sparked speculation that the two are living together. Houska already has a number of dogs and puppies at her home.

"Teen Mom 2" is slated to air on Thursday, July 9 at 10 p.m. ET on MTV.
