A Laguna Beach baby! Former MTV personality Casey Reinhardt took to Instagram on Monday, April 4, to share the happy news that she is pregnant and expecting her first child with husband Sean Brown.

“We are SO thrilled to announce we are having a baby!!!!” the excited mom-to-be, 29, wrote alongside an adorable pic of her entrepreneur hubby cradling her baby bump. “Life is truly so beautiful and exciting for us right now! We feel beyond blessed and so incredibly excited! ❤️”

The announcement comes just months after the self-proclaimed Cupcake Queen married Brown (who is the nephew of the late Nicole Brown Simpson) in a lavish ceremony in Newport Beach, California, on February 20.

As Us Weekly previously reported, Reinhardt — who made waves on season 2 of Laguna Beach as the “new girl” — wore a stunning white lace gown for her luxe wedding. Adding to the extravagance of the gorgeous seaside event, guests were treated to a fireworks display and a performance by pop singer Sara Bareilles.

“Last night was the most magical, incredible, most emotional night of my life!!!” Reinhardt captioned a breathtaking photo of the newlyweds locking lips one day after tying the knot. “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!!!”

Reinhardt, who is the little sister of Paris Hilton and Lauren Conrad’s ex Doug Reinhardt, announced her engagement to Brown last August on social media by showing off a massive teardrop-shaped rock on her ring finger. 

My fiancé!!!!! ❤️❤️❤️❤️❤️
