Lauren Conrad and William Tell are adding to their family! The Hills alum took to Instagram on Tuesday, April 2, to announce that she’s pregnant with the couple’s second child.

“It’s been hard to keep this one to myself!” Conrad captioned a photo of herself cradling her stomach. “Very excited to share that our family will be getting a little bigger this year.”

The fashion designer didn’t share a more specific due date or any other details, but whenever the newborn arrives, they’ll join the couple’s son, Liam James Tell, whom Conrad and Tell welcomed in July 2017.

Conrad first spoke about the possibility of adding to her family soon after Liam was born, telling People magazine, “I was looking at [Liam] the other day, and I was like, ‘I understand now why people keep having babies!’ We’ll probably have two.”

She also shared one of the things she loves most about motherhood — getting to indulge her inner child. “I’m just excited to play again! I can’t wait to break out the finger paints. And I’m such a Disney nerd, so I get to watch those movies with someone who is seeing them for the first time,” she said at the time.

“I worked hard to get here,” she continued. “It took a lot. And it makes me appreciate my life now and value the peacefulness. I’m really lucky. And I know that.”

Congratulations to the growing family!
