And while they seem to be experts at co-parenting, the two have both moved on with different partners. Pratt is currently dating Katherine Schwarzenegger, 39, while Faris has reportedly been seeing her Overboard cinematographer, Michael Barrett, 48.
A source told ET in July that Pratt's relationship with Schwarzenegger has become "serious quickly," after paparazzi captured shots of them kissing in public while out with the actor's son.
"[They] went from casually dating to spending much more time together," the source said at the time. "Chris and Katherine have introduced one another to their family and friends, and have been almost inseparable when they are free."
"Until he knew it was more than just casual, he wasn't introducing Jack to anyone," the source added. "Chris and Katherine are very happy together."
