Over the holiday weekend, Ana was photographed in Los Angeles enjoying a walk with Ben and the three kids he shares with his ex, Jennifer Garner. And while joining one's man for a family dog walking expedition may seem like no big deal, TMZ points out it's the first time Ana has been spotted with Violet, Seraphina and Samuel.
Ben's last serious girlfriend, Lindsay Shookus, by contrast, was never photographed in public with his children, even after years of the former couple's on-off dating.
The group appeared to be in good spirits as Ana chatted with Ben and Jen's youngest near the back and Violet kept an eye on her mom's dog, Birdie.
Ana brought her own small dog, Elvis, out to enjoy the sunshine, as well, according to TMZ.
Ben, 47, and Ana, 32, went public with their relationship in early March.
Since then, they've rarely been seen apart, though it's unclear when Ben introduced his daughters and son to Ana.
The romance comes after Ben issued a string of public praises to Jen, whom he thanked for being "thoughtful, considerate, responsible and a great mom and person" in a letter he gave Diane Sawyer to share on "Good Morning America."
The exes have both spoken publicly about their commitment to their friendship and to co-parenting their kids, all of which appears to make Ben even more of a great guy in Ana's eyes.
Last week, a source told Us Weekly the actress admires his devotion to co-parenting with Jen.
Over the weekend, an insider dished to People that Ben and Ana "are very happy together."
