Jenelle Evans is pregnant, but is she also using drugs?

According to a recent report, the Teen Mom 2 star, who struggled with an addiction to heroin years ago, was recently accused of smoking pot while pregnant.

On Monday, The Hollywood Gossip revealed that Evans and her co-stars, including her ex-boyfriend Nathan Griffith and current boyfriend David Eason, recently united in New York City to film the series' reunion special (even though the season has not yet premiered) and during the event, Evans' pregnancy and possible irresponsible behavior was a focal point.

"Griffith claims she smoked pot on several occasions while pregnant with daughter Ensley, who's due in January," the outlet revealed, citing Radar Online as their source. "Witnesses say Griffith leveled the allegation against a shocked Evans while the two of them were participating in an awkward interview segment at the reunion."

In response to the shocking allegation, Evans has reportedly denied doing anything of the sort.

"Of course he's going to accuse me of crazy things at this point," she's quoted as saying.

"She said he uses drugs," a source on the set of the reunion said.

Still, Evans insisted, "I don't know where that information came from, but that isn't true."

Jenelle Evans and her co-stars are expected to return to MTV later this year or early next year for the upcoming season of Teen Mom 2. However, at this point, the series hasn't been officilaly renewed and a premiere date has not yet been set.
