Chris Hemsworth wants to spend all his spare time with his ''fascinating'' baby.

The 'Thor' star and his wife, Spanish-born actress Elsa Pataky, welcomed India Rose into the world in May and Chris insists his five-month-old daughter is the most important thing in his life.

When asked what he does to relax, he said: ''At the moment, I hang out with my little baby. It's fascinating watching her; every day there's something different.

''Now she's becoming more and more aware of the world and that's incredible. Also I surf, train and see movies: regular stuff. My wife and I are pretty outdoorsy and adventurous; we like to keep moving.''

The couple met through mutual friends in 2010, marrying in December the same year and the pair have kept their relationship out of the public eye for the last two years.

Chris, 29, also avoids social networking sites like twitter because he values his privacy.

He added in an interview with Prestige magazine: ''I think there's a danger of being overexposed with that stuff. The mystery of who you are is what keeps people interested in wanting to see you on the screen.

''Also, it's easier for them to believe you as that character if they don't know too much about you. It's hard not to be overexposed these days with the internet, and especially when you do a tour for something like 'The Avengers' or 'Snow White and the Huntsman', where you're contracted to do an incredible amount of press.

''Besides, I'd rather be hanging out with my family than updating to people I don't know about what I had for lunch. Also, there are so many fake ones out there, which is pretty frustrating.''
