Chris Pratt and wife Anna Faris give emotional speeches at Hollywood Walk of Fame event

Actor Chris Pratt has paid tribute to his wife Anna Faris with a gushing speech at his Hollywood Walk of Fame star ceremony.

The Guardians of the Galaxy actor received his own star in Hollywood and he thanked Anna and their son Jack, four, reported In Style magazine.

"I want to thank my wife Anna, I love you. You've given me so much. You gave me the greatest star in the galaxy in my little boy, I love him and I love you," Pratt said.

"We have bonded to make this molecule that is more important to me than air or water, and without it, none of this means anything to me. With every challenge, with every day, week, month, decade, we become more bonded. You make me laugh like nobody else.

"You're very caring, and thank you for your trust and your sacrifice - and for your dedication and your heart. I will do my best to protect it, and in return, I will give you all of those things as well. You have my heart, my dedication, my trust."

Anna also gave an emotional speech about her husband, saying she was the beneficiary of all this because she gets to spend every day with "this wonderful man" "I know that if our circumstances were different and we weren't as fortunate to be standing here and living our Hollywood life, we would be happy in the woods together, I think."
