We didn't think that Louis could get any cuter, but we were wrong.

Sandra Bullock's son looked more adorable than ever today in a Batman costume. The little caped crusader was ready to fight crime and protect his doting mama from danger. Sandy, who also looked dashing in a striped black and white top, ripped, faded jeans, a Panama hat, and shades, laughed on as her little darling teetered to their car.

The loving mom looked fitter than ever, exposing her toned belly when her top slightly rode up.

Halloween must have come early at little Louis' school because he and all his classmates sported costumes. One of his friends was dressed as a viking. The trend continued throughout the day. Gwen Stefani's son Zuma seemed to be wearing a Power Ranger-esque costume, while Jaden Smith donned an Iron Man suit.

Three's a trend!
