The seemingly ageless actress took a break from filming Season 2 of "Fuller House" and celebrated her big day among friends and co-stars on the set of the Netflix hit. And it wasn't long before the party spilled over to social media.

Birthday love from my #FullerHouse family! I love you guys!! 🎂😘

There were cookies, cake and plenty of sweet sentiments to go around.

John Stamos — aka Uncle Jesse to Loughlin's Aunt Becky — shared a shot of himself and the birthday girl digging into the delicious treats.

Meanwhile, Tanner family patriarch Bob Saget went with a throwback pic of his pal.

He wished his "lifelong friend" a happy day and wrote, "You're an angel and you never age and you're the best friend a person can have." He then added, "Oh, it's Bob btw."

Of course, Joey got in on the fun, too. Actor Dave Coulier posted a cute photo of himself alongside his "BFF" — and upped the cute factor even more with a fun Snapchat filter.
