Jim Parsons and Todd Spiewak celebrated their nuptials in style.

The Big Bang Theory actor and his longtime partner looked rather dapper in custom Tom Ford tuxedos, as depicted in a series of photos Parsons posted to Instagram on Monday, two days after they tied the knot at the Rainbow Room in New York City.

The 44-year-old actor shared some of his favorite details of the special day in his heartfelt captions.

"She's our best friend, she was our wedding planner, she was our officiant and she played all three parts brilliantly this past Saturday: thank you and love you, @melissamcneeley (that Chuppah ain't bad, either, @doan_ly!)," Parsons captioned several snaps from the ceremony, crediting Amber Gress Photography.

The happy couple later changed into more festive jackets for the reception and first dance -- a white blazer for Spiewak and a burgundy velvet number for Parsons.

"Reception, first dance..." wrote the four-time Emmy winner. "Have to say thank you to #anniepsaltiras who was supposed to just be a guest but worked really hard to help us get the @tomford tuxes we loved so much AND she tied the bow ties of several guests that night. Annie is a champ and we love her."

Parsons' Big Bang Theory co-star, Mayim Bialik, attended the wedding and posted another snapshot of the duo surrounded by stunning pink and white flowers.

"What a wedding," Bialik captioned the shot, also calling out the beautiful floral canopy with the hashtag "#chupahlove." "Not a cell phone in sight. Everyone was so present which sounds pretentious but it was truly powerful for us all to just want to be there fully. Todd and @therealjimparsons, you are so loved. Also: hands down, prettiest chupah ever. Seriously."
