Queen for the day, indeed. Casey Reinhardt, who previously starred on the MTV reality show Laguna Beach, tied the knot with her longtime love, entrepreneur Sean Brown, in a lavish beachside wedding in Newport Beach, California, on Saturday, February 20.

The self-proclaimed Cupcake Queen, 29, donned an extravagant white lace gown for the affair, and wore her long blonde hair in wavy curls down her back to complement her fairy tale–like dress.

Brown, who is the nephew of the late Nicole Brown Simpson, wore a white tux and black slacks for the fete, which featured fireworks, a gorgeous ocean view and a performance by Sara Bareilles.

“Last night was the most magical, incredible, most emotional night of my life!!!” Reinhardt captioned a stunning Instagram photo of the newlyweds smooching on Sunday, February 21. “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. 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!!!”

The couple announced their engagement last August, and Reinhardt (her brother is Doug Reinhardt, who previously dated Paris Hilton) showed off some serious bling.

“My breath is taken away… I’ve never felt happier in my entire life!!!” she gushed in a caption alongside a photo of her beau down on bended knee. “I love you so much @seanmbrown1!!!! How lucky am I to have found my soulmate… I can’t wait to spend the rest of my life with you!!!!!!!!! Happiest day of my life!! I feel so blessed!!!”
