Ben Affleck seems to be in a cheery mood now, especially because he gets to be with his ex-wife, Jennifer Garner, and their three kids — Violet, Fin (previously known as Seraphina) and Samuel — just in time for Christmas.

Ben Affleck "is healthy, single and enjoying life," a source tells PEOPLE. Months after his split from Jennifer Lopez, the actor-filmmaker is enjoying quality time this holiday season with his three kids shared with former wife Jennifer Garner.

For the better part of a year, Ben Affleck’s relationship with Jennifer Lopez has been making headlines, as insiders alleged that there was marital strife between the two. That all came to a head in August when Lopez filed for divorce.
