Mirror mirror on the wall, who's the cutest Baldwin of them all? One day after Stephen Baldwin's youngest daughter Hailey turned heads at the red carpet premiere of After Earth, her cousin, Ireland Baldwin, took to Twitter to jokingly clarify that she's still the "cutest" of them all.

"Who is the cutest Baldwin? Me. Durka durka," Alec Baldwin's 17-year-old daughter tweeted on Thursday, May 30. "Yeah, sure she's pretty, but does she make you laugh and a killer PB & J?"

Hailey, also 17, was on hand at sci-fi film to support pal Jaden Smith, 14, who is currently dating her good friend Kylie Jenner, 15. "After Earth is an amazing movie and if you don't go see it there's something wrong with you," she tweeted after the premiere. "Jaden kills it!"

At the premiere, Hailey wore a short, figure-hugging black-and-white minidress with sky-high nude pumps as she walked the carpet with her dad. She and older sister Alaia, 20, are said to be close with their cousin Ireland. 

"No matter how much you think you understand a Baldwin, you really don't unless you are one," Alaia told Page Six magazine last September. "Ireland I are pretty sane for Baldwins."

Ireland was most recently spotted with boyfriend Slater Trout on a Memorial Day weekend trip to Hawaii, where the couple paddle boarded in the sun.

The pair have been spotted out and about before, engaging in some major PDA at the Coachella Music Festival this past April. "Coachella happy with Slater Trout," she captioned one photo of herself sitting on Trout's lap.
