The MTV star's five-year-old son was put into her mother Barbara's care after numerous drug issues and other charges.

Jenelle - who also has 11-month-old Kaiser with fiancé Nathan Griffith - now wants to take back full legal custody of her eldest child and have him live with her and Nathan at their home in Myrtle Beach, South Carolina.

And it seems it's shaping up to be a nasty custody battle, as the star is seen screaming at her mother over the phone in MTV's latest teaser.

Meanwhile, Kailyn and Javi are on the outs, with the mother-of-one even suggesting in the video that they were 'on the edge of divorce.'
