That's one way to celebrate Cinco de Mayo! Ireland Baldwin shared a steamy picture of herself and female rapper Angel Haze kissing via Instagram on Monday, April 5.

"happy cinco de mayo xx," Baldwin, 18, wrote. In the snapshot, the daughter of Alec Baldwin and Kim Basinger is sitting outside next to the bisexual entertainer, 22, leaning in for a passionate kiss.

Earlier in the day, the ladies appeared to stage an amateur photo shoot with each other. The twosome both took individual poses and one together. "This is what they're always talkin' 'bout," Baldwin quipped.

The back-to-blonde star—who's changed up her hair from turquoise to purple in recent months—split from boyfriend Slater Trout last March. They were first linked together back in 2013.

"Her life has gotten crazy in the past year or so," an insider told Us of Baldwin, who's a senior in an independent study program. "She is really trying to keep her momentum going as a model and she can't do that and go to school and have a boyfriend. She's young, she always had an idea that it wouldn't last forever."
