LOL! Kate Beckinsale Brought Along Ex Michael Sheen For Her Birthday Goat Yoga Session

Happy birthday, Kate Beckinsale! The actress turned 45 years old on July 26, and she celebrated in the funniest way — with a goat yoga session.

For those unfamiliar, goat yoga or "goga" is exactly what it sounds like: getting flexible surrounded by tiny four-footed animals. Kate brought along her ex Michael Sheen and their daughter, Lily, for the hilarious outing, which became her "best birthday ever." Kate and Michael dated for eight years, until their split in 2003, but they've stayed close friends ever since. She shared photos on Instagram, showing off their group session and her extra-special birthday kisses. While Kate may have made friends with the goats, Michael's session ended with some "friendly fire" on his yoga mat. Please excuse us, we can't stop laughing.

Ahead, see more photos from Kate's fun-filled day, including a peek at her Cardi B-inspired birthday cake, courtesy of her awesome daughter.
