The pair were spotted out together in Paris over the weekend, holding hands as they strolled the Saint-Germain-des-Pr s neighborhood. Jillian is traveling around Europe as Jennifer Lawrence‘s makeup artist for the Hunger Games: Mockingjay – Part 2 premieres.
The couple, who share three children – Tallula, 13, and twins Sullivan and Darby, 8 – announced their split in January.
Jillian and Patrick, 49, were married for 15 years before their early 2015 split.
“[The split] was a long time coming,” a source close to the couple told PEOPLE at the time. “They were never going to make it work, but they tried.” Adds a family source, “They have had disagreements for a long time.”
