Robert Downey Jr took time out of being Iron Man to deliver the coolest bionic limb. In a time when reality stars seem to have all the headlines it is nice to see a 'Real Star' do something pretty cool.

The 7-year-old Alex was born without one of his arms and the folks at Limbitless Solutions built him a bionic arm that looks like Tony Stark did the job himself.

I hope TMZ takes a little out of their gossip feature to give this story the kind of respect it deserves.
