Anna was out Sunday in L.A. taking a stroll with her boyfriend, Michael Barrett, and her son, Jack.

Jack looks pretty chill up on Barrett's shoulders and it shouldn't come as a surprise since Anna and Michael have been spending plenty of time together. The two were spotted just a couple weeks ago when they went house hunting together.

As for things with estranged hubby Chris Pratt, the two filed for divorce simultaneously Dec. 1 ... and they're asking for joint custody of Jack.
