Although the Teen Mom 2 star has not yet revealed the terms of her and Simms' agreement publicly, one of her latest social media posts confirms one detail of their schedule. On September 3, Messer posted a photo of her wall calendar and on it, a message read, "Corey's weekend." "We needed this," Messer captioned the photo, which also included several of her twins' activities and a couple of appointments.

Leah Messer lost custody of her twins in October but regained time with the girls months later

In October of last year, during filming on the sixth season of Teen Mom 2, Leah Messer's ex-husband, Simms, was named as the primary custodian of Ali and Aleeah, their 6-year-old twins.

At the time, it was believed that Messer had been failing to get her kids to school on time and on episodes of the show, Messer was seen struggling in the morning with her kids. She was even seen failing to feed her kids breakfast before they left for school. Three months later, after Simms and his wife, Miranda, welcomed their first child, daughter Remington Monroe Simms, Us Weekly shared a report which claimed Messer and Simms had gone back to court and came to a joint agreement for their kids.

According to an insider, Leah Messer's new agreement with Simms meant that she would have the girls from Thursday until Sunday while Simms would take care of the remainder of the week and also receive have them during one weekend each month, which Messer's Instagram photo confirmed. They "came to an agreement that works best for the girls," a source told the magazine.
