Holmes looked like she's back to her unattached mom status after Foxx recently said he was "single" amid wedding rumors.
The mysterious couple kept their relationship on the down low for years, but now, their relationship status is unclear.
Holmes, 40, and Suri, 12, looked to be making the best of the situation as they visited Moria Refugee Camp in Greece, working with women and young children.
Holmes is a global ambassador for Artolution, a community-based public art project that helps to address a variety of challenges faced by local residents.
She and Suri created art projects with the thrilled refugees.
Artolution said in a statement, "Thank you, Katie Holmes for your support AND working on the ground with us in Greece, teaching performance to refugees in the Moria Refugee Camp! Showing up and sharing this experience together. Kindness in action."
