Wuv, twoo wuv…it’s still going strong, nearly 30 years later.

Cary Elwes posted on social media Saturday the sweetest 51st birthday tribute to Robin Wright, his co-star in the 1987 cult fantasy film The Princess Bride. The two play love interests Westley and Buttercup.

Elwes, 54, posted a photo of the two sitting in their costumes on their outdoor set, with her wearing the red dress she sported when her character gets kidnapped under a matching puffer coat. The actor sports an olive green parka over his black pirate’s outfit, as well as a cap.

“Happy Birthday Robin,” Elwes wrote. “You were a princess when we met, and now you’re lovelier than any queen. Please join me in wishing her the very best. @robingwright.”

Wright, now known for her role on Netflix’s House of Cards, did not respond online.

The Princess Bride celebrates its 30th anniversary this fall.

Elwes, Wright and other former cast members last reunited at a 25th anniversary event for the movie at the 2012 New York Film Festival.
