Ashton Kutcher is eager to mentor young people.

The 35-year-old actor, who is dating 'Black Swan' star Mila Kunis, has signed up to, a website offering users the opportunity to video chat with professionals from different industries and gain insight for their own well-being and success.

A source told E! News: ''Ashton is passionate about giving back and being a mentor to young people. It's a cause that is very important to him.''

The 'Two And A Half Men' star goes by his real name Christopher Kutcher on the site and users will be charged just $5 to chat with the actor for one-hour for the first session and $10 for any additional sessions.

But the site currently says he has no upcoming availability and users requesting time must sign up for the waiting list.

A spokesperson for Popexpert declined to comment on the actor or his role with the website.

The heartthrob is set to have more free time in his busy schedule soon as he and Demi Moore finally signed their divorce papers last week.

The former couple - who separated in November 2011 - have reportedly reached a settlement to dissolve their marriage after a near two-year court battle, and are expected file the documents imminently in Los Angeles.

A source recently said: ''Ashton and Demi have finally signed their divorce agreement. They are about to file paperwork with the court that will formally end their marriage.''
