Laguna Beach alum Casey Reinhardt is going to be a mom of two.

The 31-year-old television personality announced in an Instagram post Tuesday that she's pregnant and expecting another baby with husband Sean Brown in January.

"Sean, Kensington, and I are sooooo thrilled to finally announce that angel baby number two will be joining our family in January!" Reinhardt captioned a photo with Brown and daughter Kensington, who turns one Aug. 16.

"We are beyond excited for our new precious addition and we feel so incredibly blessed!! #BabyBrownNumberTwo #January2018 #15weekspregnant #TwoBabiesUnderTwo #LifeisSoGood #soakingupeverysecond," she added.

Reinhardt and Brown celebrated Kensington's birthday with family and friends at an early birthday party Sunday. Reinhardt had dedicated a sweet message to her daughter on Instagram a couple days previous.

"My precious Princess I love you so much and I can't believe you are going to be ONE in a few weeks!" the star captioned a photo of her baby girl.

"This has been the best year of my life and I love love love being your mama!!! #KensingtonKellyBrown #11.5Months #soakingupeverysecond #mylove #sososoblessed," she gushed.
