"My Girl" is engaged.

Oh God. I really am old.....
Anna Chlumsky is going from My Girl to soldier's bride. The 26-year-old actress, best known as Macaulay Culkin's gal pal Vada in the 1991 film My Girl, is engaged to Shaun So, 26, an Army reserve member who served in Afghanistan, she tells PEOPLE. The couple, who live in Brooklyn, N.Y., are currently planning a wedding to take place next March. "Shaun's family is Chinese, and my family is Catholic. So we're going to do a fusion of the two cultural traditions," Chlumsky said Thursday night at the Conde Nast Traveler Readers Choice Awards.
