Janelle Evans is where she wants to be -- back home. After entering rehab last week, the Teen Mom 2 star, 21, has been reunited with her son and returned to Twitter.

The MTV star tweeted a mother and son photo on Sunday, March 10 of her 3-year-old son Jace flashing the peace sign from his car seat behind her in a car. The next day, she shared a photo of herself cuddling Jace in bed, captioning the shot, "Just where I wanted to be. Morning sunshine."

Evans had previously signed off from Twitter on March 2. "This is for you Jace, no one else," she wrote, hinting at an imminent, much-needed rehab stay. "If anyone deserves this you do. Love you so much buddy. Bye everyone."

The MTV star's attorney, Dustin R. T. Sullivan, said in a statement to E! News on March 6, "Jenelle is in a rehabilitation treatment facility in North Carolina to address any addiction issues for drug use." He did not comment on how long she planned to stay in the facility.

Radar Online reports that Evans left treatment after four days. While she was away, her estranged husband Courtland Rogers was arrested for a previous assault charge his wife filed against him. But it looks like he's out as well.
