Anne Hathaway has joined the swelling ranks of celebrity do-gooders, the New York Daily News reports.

The likable Devil Wears Prada star traveled to Nicaragua this week to lend a hand with a vaccination program for kids.

"Hepatitis A is actually becoming a huge problem in Nicaragua. This has been an eye-opener for me. Even if I weren't an actress, I'd do it just to help," Hathaway said.

Hathaway, 23, reportedly made the trip at the request of her boyfriend, real estate executive Raffaello Follieri, whose charitable organization is behind the vaccinations.

"I was given the gift of being a successful actress, and I feel like I should use my voice," she said.

Anne gained widespread recognition for her starring roles in The Princess Diaries and its sequel, playing a teenage girl who discovers that she is a member of royalty.

She branched out in 2005 with roles in Havoc and Brokeback Mountain, where she played the wife of Jake Gyllenhaal's character. The Devil Wears Prada is Hathaway's biggest success to date, and she will soon star in Becoming Jane, in which she plays author Jane Austen.
