Blonde and beautiful must be in the Baldwin girls' DNA. Alec Baldwin's daughter, 17-year-old Ireland, has been making waves (and headlines) as an aspiring model in recent months — and now her gorgeous cousin Hailey, also 17, is turning heads on the red carpet. On Wednesday, May 29, Stephen Baldwin's youngest daughter wowed the crowd at the Mercedes-Benz hosted New York City premiere of After Earth, starring Will and Jaden Smith.

Arriving at the Ziegfeld Theater before the movie, the blonde stunner rocked a short, fitted, black-and-white frock with sky-high nude platform heels. She was accompanied by her dad — the youngest of the four Baldwin brothers, behind Alec, Daniel, and William — who wore a black suit, blue T-shirt, and dark sunglasses.

"After Earth is an amazing movie and if you don't go see it there's something wrong with you. @officialjaden kills it!" Hailey tweeted after the premiere, giving a shout-out to Jaden Smith.

Jaden, 14, is dating Kylie Jenner, 15, who is a friend of Hailey's. Earlier in the week, Kylie and Hailey met up with a few other pals for pizza in New York's West Village.

"Day with my girls," Kylie tweeted on Tuesday, May 28, along with a link to a picture of the stylish group.

Hailey is Stephen Baldwin's daughter with wife Kennya Baldwin, whom he married in 1990. The couple also have an older daughter, Alaia, 20. Both girls are said to be close with Ireland.

Speaking about their famous family in an interview with Page Six Magazine last September, Alaia explained the bond between the younger Baldwin cousins. "No matter how much you think you understand a Baldwin, you really don't unless you are one," she said. "Ireland and I pretty sane for Baldwins."
