The actor and model Clair Meek walked down the aisle in a traditional Scottish ceremony in Dundas Castle, near Edinburgh, in front of friends and family.
Buckley, wearing a green and black tartan kilt, was spotted in the grounds of the castle with his blushing bride, who was wearing a lace vintage gown.
Actor and guest Danny Dyer tweeted a snap of the happy couple enjoying their first dance on his Twitter.com page, and wrote, "A lovely cute couple.I wish @RealJBuckley & the lovely @Clair_Meek all the best.I almost wanna get married. (almost)."
The actor's Inbetweeners co-stars Simon Bird, Joe Thomas and Blake Harrison also attended the reception.
The newlyweds became parents to son Harrison last October (11).
