Happy Birthday, Stella McCartney!

The English fashion designer turns 45 today, and judging by her ledger of famous (and fabulous) friends, McCartney is certainly going to be celebrating in style.

McCartney established her world famous fashion line 15 years ago, and she’s been a household name ever since—and not just because of her famous dad, Paul McCartney. Stella has made lasting contributions to the world of fashion and, well, the world in general—she’s a lifelong vegetarian and an active supporter of many charitable organizations.

In addition to a flourishing career and happy family life (McCartney has four children with husband of 13 years, Alasdhair Willis, plus her rock star dad is the king of cool), the successful Brit has a social group to die for. Whether posing together at awards shows or casually goofing around, McCartney is sure to have a star-studded posse by her side.

In honor of her milestone birthday, here’s a collection of McCartney’s best moments with her unbreakable girl squad.
