Former "Laguna Beach" star Casey Reinhardt is pregnant with her first child.
The 29-year-old MTV personality made the announcement on April 4 via her Instagram.
In a cute snap, Casey poses in a tight-fitting red dress which shows off her bump, alongside her entrepreneur husband Sean Brown, who is the nephew of the late Nicole Brown Simpson.

Accompanying the photo, Casey wrote a sweet message revealing their happy news.
"We are SO thrilled to announce we are having a baby!!!!
"Life is truly so beautiful and exciting for us right now! We feel beyond blessed and so incredibly excited! ❤️"

She wore a white lace gown for the seaside nuptials and guests enjoyed fireworks and a performance by pop star Sara Bareilles.
Casey shared images of her wedding day on Instagram, along with some gushing words about her man.
In one snap of the couple sharing a kiss, posted the day after the wedding, she wrote, "Last night was the most magical, incredible, most emotional night of my life!!!"
She went on, "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!!!"
Casey is the sister of Doug Reinhardt, who previously dated Paris Hilton and Lauren Conrad.
