The attention-seeking antics of Jenelle Evans may cause MTV to pull the plug on Teen Mom 2. The controversial cast member has been making news in the past few months for behaving in a way that some feel are desperate attempts to stay famous.Sources close to the show are telling the NY Post that producers feel Jenelle has become a liability. Since November, Evans has become pregnant again, gotten married, lost her baby, and publicly demanded a divorce. Most recently, the 21-year-old partied at a bar with her ex-fiance hours after giving her Twitter followers a live play-by-play of her miscarriage. The show is supposed to act as a cautionary tale for young women but seems to have turned into a sideshow documenting the troubled life of a young mother. Jenelle has been arrested seven times and gone to rehab twice since first appearing on MTV. At present time, there has been no official cancellation from the network but a fourth season of the show has already been filmed and is supposed to air on MTV sometime this year.
