TMZ has learned Jesse James was right by Sandra Bullock's side when she posed with her baby boy for that People photoshoot.
Sources tell TMZ Jesse was not only present ... he was "incredible with both Sandra and Louis" -- and created a "healthy, loving and positive atmosphere."
Now get a load of the timeline. We're told the photos were taken March 9 -- two days after the Oscars ... and just a few days before the scandal broke.
So Sandra was apparently oblivious to Jesse's alleged affairs when the pics were snapped.
Alas, we've figured out what was really going on when a photographer was snapped carrying baby clothes into Sandra and Jesse's home on March 9.
Now, the million dollar question -- are there photos of Jesse and little Louis Bardo floating around? We're guessing since Jesse was there -- and at the time expected to co-parent with Sandra -- no way he wasn't in some of the shots. Interesting the way it ended up looking like a single mom shoot.
