Pucker up! 6 unforgettable girl-on-girl kisses

An Instagram photo is worth a thousand words. One of a hot female celeb kissing another hot woman — well, that just leaves people speechless. Alec Baldwin’s daughter, Ireland Baldwin, set tongues wagging this past week when she posted a photo of herself kissing singer/rapper Angel Haze.

Here, our favorite A-list girl-on-girl smooches.

Ireland Baldwin & Angel Haze

She’s no longer Daddy’s little girl, that’s for sure. Eighteen-year-old Baldwin recently broke up with her paddle surfer beau, Slater Trout. But a photo captioned “happy cinco de mayo xx” with her and Angel Haze (who identifies herself as pansexual), tenderly locking lips, suggests she’s not wasting time wallowing.

Britney Spears & Madonna

It’s been almost 11 years since Spears and Madonna locked lips at the 2003 MTV Video Music Awards, but the image is forever ingrained in our memories. Truthfully, it’s the happiest we’ve ever seen Brit Brit look!

Cara Delevingne & Michelle Rodriguez

What’s an NBA game without a little PDA? Supermodel Delevingne and actress Michelle Rodriguez fueled the rumors of a sapphic love affair by sloppily groping and making out courtside at a January Knicks game. Slam dunk for love!

Charlize Theron & some auction winner

During a 2009 charity event, Charlize Theron couldn’t get bidders to go above $30,000 for a trip to South Africa. So she did what any good samaritan would do — auction off a smooch, too. “I’ve got t-ts, for God’s sake,” she said at the time. Outbidding a man by $5,000, a lucky woman got a 20-second lip lock with one of Hollywood’s most beautiful, for the small fee of $140,000.

Meryl Streep & Sandra Bullock

Sandra Bullock laid one on Meryl Streep at the 2010 Critics’ Choice Awards after they both were named Best Actress nominees. The question is: Who is the best kisser?

Miley Cyrus & Cara Delevingne

It may be less of a kiss, more of a game of tonsil hockey. Miley Cyrus tweeted a photo of her and Delevingne kissing in December. Two things are certain: Ms. Delevingne sure does make the rounds. And oh my God, can we never escape Miley Cyrus’ tongue?!
