Thor star Chris Hemsworth had no problems staying grounded as he shot to fame as the star of Star Trek - he'd come off set and have to babysit his agent's kids.
The Aussie hunk fell on hard times while he was chasing his Hollywood dream and agreed to look after his agent's children in return for board and lodging.
And he was still living with his dream maker while he was awaiting his first pay cheques as the star of J.J. Abrams sci-fi blockbuster.
He reveals, "I remember shooting Star Trek and coming off the bridge of the Enterprise (on set spaceship) and thinking, 'I've made it, this is it...' And then dirty nappies (diapers) welcomed me at home and (there were) kids running around that I had to look after."
