Actress Mila Kunis revealed Thursday that she has been playing a prank on Vice President Pence by donating to the women's health-care provider Planned Parenthood in his name.

In an interview on TBS's "Conan," Kunis says that she set up a monthly donation to Planned Parenthood that sends Pence a letter thanking him for his donation every month.

"I disagreed with some of the stuff that Pence was doing and was trying to do," Kunis said Thursday.

"And so, as a reminder that there are women in the world that may or may not agree with his platform, I put him on a list of reoccurring donations that are made in his name to Planned Parenthood," she added to cheers from the audience.

"So this happens every month?" host Conan O'Brien asked, laughing.

"Every month, to his office, he gets a little letter that says 'an anonymous donation has been made in your name," Kunis responded. "I don't look at it as a prank, I look at it just as, I strongly disagree [with him], and this is my little way of showing it."

Kunis, who stars in the popular animated series "Family Guy," is a Democrat who has supported former President Obama and liberal causes in the past.

Republicans have fought for years to stop any federal money from going to Planned Parenthood, which is the nation's largest abortion provider. The organization gets federal reimbursements for providing women's health services, but not for abortions.

Pence is a longtime opponent of abortion rights.

In March, Pence cast a tie-breaking vote in the Senate to move forward with an effort to nix an Obama-era rule that blocked states from defunding health-care providers for political reasons.
