Leah Messer and Chelsea Houska used to be quite close, but up until recently, they were reportedly feuding.

According to a new report, the Teen Mom 2 co-stars had a falling out some time ago, around the time Messer was accused of hiding a drug addiction, but last week, Messer confirmed their friendship was back on track.

"Teen Mom 2 star Chelsea Houska just got finished feuding with costar Jenelle Evans, but now it looks like she was in the middle of another fight with her other castmate Leah Messer," Mstars News reported on Saturday. "Leah recently shared a text with her Instagram followers showing Chelsea apologize to her for not being a better friend."

In the message to Messer, Houska told her co-star she missed her, and was so proud of the progress she's made.

"I'm so so so happy for you and it's so amazing see how f**king great you are doing and to just talk to you and hear everything from your side. I'm sorry I wasn't a better friend through everything... I look up to how strong you are... I couldn't imagine pulling myself out of such a hard time like you did," Houska wrote. "So be proud of yourself, and know that I'm so insanely happy to see you back to yourself. Love you!!"

Also on Instagram last week, Messer shared a road trip with fans.

"Getting ready for a road trip with these two gorgeous girlies!" Messer wrote on Instagram on Friday. "It's Gracies last competition and I will actually say I'm glad cheer season is over. Haha NOW, Bring on the TBall."

As the weekend went on, Messer continued to share photos of her twins, one of which featured the girls getting ready to play in a pool, and another of them eating dinner.
