Lauren Conrad is going to be a mom again! On Tuesday, the fashion designer announced that she is expecting her second child with husband William Tell. "It's been hard to keep this one to myself!" she captioned a photo of her cradling her growing belly. "Very excited to share that our family will be getting a little bigger this year 👶🏼" The couple first tied the knot in September 2014, and welcomed their son Liam James Tell in June 2017. Congrats to the pair on their growing family!
