Leah Calvert Considers Getting Pregnant? 'A Baby Boy Would Make [Jeremy] Happy'

As Leah Calvert's marriage issues continue to play out online, she and the rest of the cast, including Jenelle Evans, Chelsea Housk and Kailyn Lowry, have started filming scenes for Teen Mom 2 season six, which will premiere next year on MTV.

'Teen Mom 2' Star Leah Calvert Reportedly Signs On For Season Six

In addition to her marital problems, which reportedly stem from Calvert's hookup with Robbie Kidd, Calvert is currently fighting back against claims she's abusing prescription pill medication. Although her issues have been kept somewhat private for the last couple of months, they are bound to take the forefront in Teen Mom 2 season six.

“Leah knows she won’t be able to hide any of this from the MTV crew,” the insider explained. “Jeremy is constantly traveling for work across the Midwest, so they really don’t talk right now.”

As for her reported drug problem, Radar's source claimed Calvert is "desperately trying to cover it up.”

“It’s her dirty little secret, and she’ll never admit she takes pills other than those prescribed by a doctor for a botched epidural,” the source said.

When it comes to the rest of the cast, things are far less dramatic. Evans and her boyfriend are raising a family, Houska has a new boyfriend and Lowry has gone back to college.
