Some celebrity couples have compatible zodiac signs, while others share the same birth month. But these four duos get to celebrate another trip around the sun on the very same day as their partners.
Longtime loves Michael Douglas and Catherine Zeta-Jones were both born on Sept. 25, while Oscar winner Adrien Brody and fashion designer Georgina Chapman celebrate their shared birthday on April 14.
Nick Lachey — who has celebrated 20 birthdays alongside his wife, Love Is Blind co-host Vanessa Lachey — has embraced the tradition as an opportunity for double the celebration every Nov. 9.
“Well, this is officially 20 straight years celebrating another trip around the sun with you!!” he wrote on Instagram in November 2025. “Truly, it is so special each and every time we get to wake up and whisper Happy Birthday to each other.”
Below, here are four celebrity couples who share the exact same birthday.

Fatal Attraction star Douglas was born on Sept. 25, 1944, while Wednesday actress Zeta-Jones was born 25 years later to the day. The couple tied the knot in 2000 and welcomed two children together.
The duo have celebrated their shared birthday with several sweet tributes over the years. Most recently, Zeta-Jones marked her husband’s 82nd birthday and her 57th in September 2026 by posting a photo of them kissing in tropical blue waters.
“Happy Birthday darling! A birthday kiss to my husband Michael, sharing this special day with you, is as special as the day itself,” she captioned the post. “Love you😘😘.”
Meanwhile, Douglas shared a heartfelt excerpt from his 2026 memoir, One Helluva Ride, on Instagram, writing, “I had never fallen in love on a movie screen before. Until I saw Catherine. She was magic, in a way that went beyond beauty. And I was certain, as much as I had ever been about anything, that she was the one.”
He continued, “It’s the kind of moment that only comes around once in your life, if you’re lucky. The one time that you know, without any doubt in your mind, that you’re meant to be with someone. Happy Birthday Catherine! I love you always and forever! ♥️.”
