There may be trouble in paradise for Brian Austin Green and Megan Fox.

In recent weeks, rumors have swirled about the couple splitting, as eagle-eyed fans noticed Green, 46, out and about without his wedding ring, as well as Fox, 34, recently being spotted with rapper Machine Gun Kelly.

On Saturday, the "Beverly Hills 90210" star added to the confusion with a cryptic post on Instagram.

An error occurred while retrieving the Instagram post. It might have been deleted.

The photo in the post captured a butterfly resting on a purple flower.

"Eventually butterflies get bored sitting on a flower for too long. They start feeling smothered," the caption read. "It’s a great big world and they want to experience it."

Although they're spending time apart, the source said, "they don't plan to file [for] divorce right now."

Fox and Green -- who have shared three children: Noah Shannon, 7, Bodhi Ransom, 4, and Journey River, 3 -- have been plagued by split rumors throughout their relationship. Fox filed for divorce before they reconciled before the birth of their third child.
