With her marriage to Jesse James officially finished, Sandra Bullock continues moving forward with her new guy ... adorable six-month-old son Louis.

In the photo below, the new mother and her adopted son, who hails from the city of New Orleans, prepare for takeoff in Austin, Texas, on Saturday.

James and Bullock actually adopted Louis together before his cheating ways were exposed. After they split, both agreed she would raise him alone.

Jesse has bought a house in Texas too, however, with the hopes of keeping Sandra in his life for his older kids' sake. Maybe he'll see Louis as well?

Anyway, everybody together now: Awww ....

Sandra Bullock is going to be the best mom.
