Jesse James didn't hide from photographers as he went for a walk on Sunday with 6-year-old daughter Sunny.

The two were spotted on the lot of his West Coast Choppers shop -- where he returned to work for the first time since reports of his alleged affair began circulating -- in Long Beach, Calif.

As Sunny rode her bike, James -- in overalls and wearing his wedding ring -- was also joined by his dog, Cinnabun.

Late last year, the biker, 40, won a contentious custody battle over Sunny against ex-wife Janine Lindemulder.

Sandra Bullock, 45 -- who has not been seen since news broke -- had been helping James raise Sunny since early 2009 while the porn star was in prison for tax evasion.

Now, some reports claim Lindemulder is returning to court to reclaim custody.
