Have mercy!

Lori Loughlin and John Stamos, newly reunited on the set of "Fuller House," celebrated Loughlin's 51st birthday Tuesday, and shared some sweet photos of the special occasion. (The actress has not aged since her "Full House" days, we might add.)

In one image, Stamos — flanked by co-stars Bob Saget and Dave Coulier — presents her with a gorgeous bouquet of roses. "51 Flowers for our favorite fun girl. #HappyBirthdayBecky," Stamos wrote on Instagram.

In another shot — which Stamos captioned "Running from birthday woman!!" — Loughlin jokingly chases her onscreen husband through a parking lot.

Loughlin also shared a snap of a birthday card signed by various cast members, including Blake Tuomy-Wilhoit and Dylan Tuomy-Wilhoit, who will evidently be reprising their roles as Uncle Jesse and Aunt Becky's sons, Nicky and Alex. (Dylan even wrote "Love ya, 'mom.'")

And they might not be the only "Full House" twins to return. Despite previous reports that Mary-Kate and Ashley Olsen would not be seen on "Fuller House," Netflix executive Ted Sarandos said they're "teetering whether or not they'll be around" during the Television Critics Association summer press tour Tuesday.

Would that excite us? You got it, dude.
