Demi Moore Wore a Tiny Snake-Print Bikini While Celebrating Her Dog Pilaf's Birthday

Her sweet girl is officially four years young.

Birthday wishes are in order for a very important member of Demi Moore's family. The Substance actress took to Instagram to wish her tiny little dog, Pilaf, the happiest of birthdays—and snuck in a quick peek at her wearing tiny bikini in the process.

"Happy birthday to everyone’s favorite! The icon, the cover girl, my everything @pilaf.littlemouse ♥️ You are so loved!" Moore captioned a video supercut with several moments from her and Pilaf's life together. One of the moments of the video featured Moore and Pilaf enjoying a clear sunny day on the beach—Pilaf, naturally, wore her light brown and white fur coat for the occasion, while the 62-year-old donned a tiny snake print bikini that showed off cleavage up top.

Over on Pilaf's official Instagram, she celebrated her special day with a post that read, "I AM 4 TODAY!!! 🍰 I AM A SCORPIO — I AM A LEGEND. Love my hive #Pilafnation pls comment your favorite pic of me!!"

Pilaf has captured hearts everywhere due to Moore taking her out to virtually every type of event. "I can take Pilaf everywhere. She’s literally been to Broadway shows, museums, the French Open, art openings, restaurants," she told Vogue. "She’s a service animal, so she’s allowed to go everywhere. She’s flown to Europe 14 times."

The 62-year-old continued, "We almost got thrown out of the Sisi Museum in Vienna [until] I found her official card, because I didn’t register her. She saw Romeo and Juliet with Tom Holland—loved it. She saw Funny Girl and Appropriate with Sarah Paulson."
