It's been a busy week for a number of MTV's Teen Mom 2 stars, and not all of it is good news.

Teen Mom 2 Star Wants Custody Of 1st Son Back

Adam Lind, ex-boyfriend to Chelsea Houska on the show and father to four-year-old Aubree has been arrested again. The 23-year-old Lind was arrested Friday after some problems with his daily drug and alcohol testing.

According to the UK's Daily Mail, Lind was taken to Minnehaha County Jail in Sioux Falls, S.D. Monday after either failing the drug and alcohol test or failing to show up all together.

Teen Mom 2 Star Jenelle Evans Could Be Leaving Series To Focus On Education

This is Lind's second arrest since May, when the star was taken in on driving with a revoked license. Lind has a history of driving related incidents involving alcohol. Lind was supposed to spend the weekend with his daughter, but instead spent the weekend in jail.

One Teen Mom 2 star looking forward to some "one on one" time with her child is Kailyn Lowry, who has spent the last few weeks on the road promoting her book, Pride Over Pity.

"Spending one on one time with your kids is so important when you have more than one child," claimed the star via Twitter on Sunday.

"Can't wait to have our mommy/son date with Isaac when he gets back from his dad's!" wrote Lowry a few minutes later, referring to the older of her two young sons.

While on Twitter, Lowry reposted a statement wishing fellow Teen Mom 2 star Jenelle Evans luck Monday.

Evans is due to give birth to her second son, Kaiser, Monday, though the MTV star had yet to go into labor. This will be her first child with boyfriend Nathan Griffith. Her five-year-old son, Jace, still lives with Evans' mother as she has legal custody of the child.

 Teen Mom 2 returns to MTV for season five July 9 at 10 p.m. ET/PT.
