Reality TV star-turned-cupcake chef Casey Reinhardt married her longtime boyfriend Sean Brown during a gorgeous ceremony and reception in Orange County, Calif., Saturday, reported People. The former star of MTV's hit series "Laguna Beach: The Real Orange County" took to Instagram to share photos of her "dream" wedding.

The newlywed shared a sweet photo from her big day as she shared a kiss with Brown, while fireworks went off over the ocean in the background. The 29-year-old cupcake queen wore a lace, long-sleeved wedding gown designed by Zuhair Murad, and completed her bridal look with a sparkling flower crown and a long, white veil. Brown wore a white tuxedo with a white boutonniere.

"Last night was the most magical, incredible, most emotional night of my life!!! I became Mrs. Casey Beau Brown and I get to spend the rest of my life with the most amazing man who ever walked this earth," Reinhardt wrote in the caption of the shot. "I'm so happy, so in love, and so overwhelmed with emotion just thinking about how beautiful the rest of our lives are going to be together. You are my angel on earth @seanmbrown1 and I'm the luckiest girl in the world to be your wife!!! 2-20-2016.... #CaseyandSeanSayiDo"

She shared video clips featuring some details from her wedding, including lush white floral table arrangements, ceiling arrangements and a white flower wall by White Lilac Inc., and a fireworks display that went off just after Reinhardt and Brown said "I do." Guests were also treated to a performance by singer Sara Bareilles, who performed the couple's song "I Choose You."

"I cried uncontrollably, it was so incredibly touching!" Reinhardt wrote in the caption. "Thank you for being apart my and @seanmbrown1's dream wedding @sarabareilles!! You made it so special singing my favorite song!!"
