Cara Delevingne may have turned 26 back on August 12, but she's only just posted pictures from the party, so let's check in on the model-actress and how her new life chapter is shaping up, eh?

Via Instagram, Delevingne shared photos from her birthday bash, in which she and famous friends like Zoë Kravitz, Margot Robbie, Sienna Miller, and Kate Beckinsale pose poolside with...a mermaid. Or, a woman in a mermaid costume. We won't make a definitive call on whether Delevingne hired a woman to play-act as a mermaid or caught an actual woman of the sea and is keeping her prisoner. Either way, everyone seemed to be having a great time. The birthday girl captioned the photo series, "It was my birthday a week ago and I am still giggling with MERmazing memories."

According to the Daily Mail, the exclusive party was held in the South of France, where Delevingne really played up the high/low thing, wearing a dress held together with 24-karat gold rings and blowing out the candles on a cake...shaped like a pot leaf.

Pal Paris Jackson also took to Instagram to celebrate 26 years of Cara, posting a series of photos of the two of them (all visible here, on Elle) and adding the messages, "happy belated birthday i love you @caradelevingne" and "i'm so proud of you and all you do. here's to another year of life, so lucky to have you in mine!" Jackson and Delevingne were reportedly dating earlier this year, but, per Jackson's own tweets, the two were never exclusive.

But cornrows aside (or will she pull a Kim Kardashian and claim they're "Bo Derek braids"?), the biggest new development in the young star's life is certainly her relationship with Pretty Little Liars star Ashley Benson. There's been no official comment from either party—no word on exclusivity—but they made out at the airport, so draw your own conclusions.

Benson was even wearing a necklace with a "C" on it, bringing to mind a certain Taylor Swift lyric. Aww. Happy birthday, Cara.
