Ashton Kutcher 'Just Wants to Move On,' Makes Birthday Vow

"Two and a Half Men" star Ashton Kutcher has celebrated his 34th birthday with intentions to "move on" from estranged wife Demi Moore and a vow to improve the world.

"I'm determined this year to do everything in my power to make the world a better place," said the actor in a video he posted to "I want to start by getting right after it today."

Kutcher posted the video Tuesday thanking fans for their birthday wishes and informing viewers that he would match any donation made to DNA, the foundation he and Moore founded.

"As you may or may not know I have a foundation that focuses on ending the sexual exploitation of children and any help that you could give toward that would be an amazing present," said Kutcher, who promised that he would match each dollar donated to the cause.

Additionally, a report by Us Weekly reveals that the actor is striving to recover from his divorce from Moore.

"He just wants to move on," said a source close to Kutcher speaking to the magazine. "He cares about Demi and would help if asked, but he's not a part of her life anymore."

Moore is currently being treated for "exhaustion" and an undisclosed location after smoking an unknown substance and suffering from convulsions late last month.

Also on his birthday Tuesday, Kutcher celebrated with his coworkers on the set of "Two and a Half Men" with a birthday cake.

"Love my coworkers," said Kutcher on his Twitter account along with a photo of the cake.

Kutcher returned to the set of the CBS sitcom on Jan. 31 after a trip to Brazil.

"Ashton was in a great mood and seemed to be excited to be back at work," said an eyewitness speaking to People magazine at the time.
