Earlier this month, the former couple was spotted reuniting for the first time following their June separation. McDermott announced his split from Spelling after 18 years of marriage in an Instagram post at the time, citing that the pair "have decided to go our separate ways.” He deleted the post shortly afterward.

In photos obtained by Page Six, Spelling and McDermott, 57, were snapped speaking with each other at a park in Agoura Hills, California.

Representatives for both Spelling and McDermott did not immediately respond to PEOPLE's request for comment.
