After much speculation, Teen Mom star Jenelle Evans is pregnant once again, and her best friend confirmed the news. 

"Jenelle is pregnant. She never wanted it to get out," the MTV star's best friend Jennifer told Radar Online about the news that Evans and her boyfriend Nathan Griffith are expecting a baby together.

A source also revealed to E! News that the 21-year-old's second pregnancy was planned and the reality star told her friends over the summer that she and Griffith "were trying" for a baby. 

Jenelle's mother, Barbara Evans has custody of her son Jace. 

"It sucks. I know she wants to prove she's doing better, but having another baby without custody of her first isn't helping," the source says

The reality star was thrown in jail after she failed a drug test in August. Griffith was also arrested on Septemeber 7 for DUI, the same time Jenelle was captured on a dash-cam video telling cops they were speeding because she was "trying to have sex" with him.

But Jennifer claims that "MTV leaked" the pregnancy news, adding that Jenelle did not want the news released yet. It was published "against her will. Jenelle didn't even want people to know that MTV was filming her after they found out she was pregnant."

Griffith already has a 2-year-old daughter, Emery from a previous relationship.
