Abigail Breslin Is Little Miss Stunning In A Little Black Dress

Talk about growing up gorgeous!

Abigail Breslin, who you may still remember as Olive Hoover from the 2006 film "Little Miss Sunshine," looked grown up and beautiful at the 11th annual Project Sunshine benefit celebration in New York City Tuesday, April 29.

Breslin, 18, rocked an off-the-shoulders, body-hugging black dress, paired with a loose braid and red lip.

The former child star is doing all sorts of good these days, particularly off-screen. According to the Daily News, she donated $10,000 last week to the Cristian Rivera Foundation, which seeks to find a cure for diffuse intrinsic pontine glioma, a rare form of cancer. Breslin chose this cause, adds the Daily News, because a family friend of hers died from the disease last year.
