Ashton Kutcher is using is combining his fame and his experience in entrepreneurship to help new fathers across the country.

The Two and a Half Men star is set to appear as a "guest shark" on the hit ABC series Shark Tank, and a source tells ET that the 37-year-old new father made sure to champion one of his most outspoken causes during the taping of his episode: gender equality when it comes to having diaper changing stations in men's restrooms across the nation.

Apparently it was an issue Kutcher brought up frequently, as a way of using his public platform to advocate for his cause. It's always nice to see a father fighting for advancements to benefit America's families.

An eyewitness reports that Ashton's wife Mila Kunis and their baby daughter Wyatt Isabelle joined him for the taping, and, although the two were not married at the time, Ashton reportedly referred to Mila as his wife.

For the most part Mila and Wyatt stood and watched just off set during filming. However the new parents, who welcomed their little girl in October, hung out during production breaks and ate lunch with the other Sharks -- including billionaire Mark Cuban, who supposedly got along well with Ashton.
