Let's make this birthday one to remember.

45 years old (Born on September 15, 1979)

Happy Birthday, Nicole! From your iconic Gossip Girl days as Isabel Coates—mastering the art of Upper East Side sass—to continuing to charm us with your timeless style and wit, you've truly made every moment unforgettable. Honestly, Blair Waldorf had nothing on you!

Here's hoping this year brings even more fabulous adventures (and fewer gossip scandals). May it be filled with laughter brighter than Serena's wardrobe choices and success sweeter than Dorota’s loyalty. Keep dazzling everyone around you—you’re forever our favorite scene-stealer.

XOXO—and cheers to another glamorous chapter ahead!
