According to a new report, Simms' current arrangement with Messer and their daughters won't allow him to spend Easter with his children, which could pose a problem for the former couple.

In response to the tweet above, International Business Times claimed Simms was in charge of caring for the twins from Monday until Thursday, while Messer was left with the second half of Thursday, and weekends (Simms also has the girls on the second weekend of each moth). Still, that doesn't necessarily mean they are headed for a feud -- especially considering recent reports claim the two are on good terms.

The new arrangement “is working out just fine,” a source close to the former couple told Radar Online in February. “Everything is running smoothly.”

“Both Leah and Corey are very happy with the new schedule,” the source added. “They are on great terms.”
