The Hills cast is growing. Just weeks after Whitney Port and Lauren Conrad each welcomed their first child, both boys, Conrad's former boyfriend, Jason Wahler, and his wife, Ashley Slack, have become parents to a baby girl.

On August 22, Entertainment Tonight confirmed the news of the child's arrival, revealing that Wahler and Slack's daughter, Delilah Ray Wahler, arrived on Monday, August 21 at 8:16 a.m. in Newport Beach, California, which is just a short drive away from Laguna Beach, where Wahler initially found fame.

"We are so unbelievably in love! We are so excited to start this new chapter of our lives and never thought we could love someone so much," the couple told the outlet in a statement on Tuesday.

Delilah Ray Wahler weighed in at 7 lbs., 12 oz. and measured 21 inches long and is already a "daddy’s girl."

Wahler and Slack tied the knot in October 2013 and revealed they were expecting their first child together in February. At the time, Wahler told Entertainment Tonight that he was looking forward to hearing his child's first words and seeing their first steps.

"All of it is such an incredible journey and blessing we get to be a part of," Wahler said. "We are so overjoyed and excited for this baby! We absolutely LOVE kids and are so happy to finally be starting a family of our own."

Earlier this month, after welcoming son Liam in July, Conrad debuted the first photos of her child on the cover of People magazine.

“I feel so spoiled,” she said. “Liam is such a good baby. I’m sleeping three to four hours at a time. This morning I was up at 4 a.m. and I wasn’t even tired, so I cleaned the kitchen and did some cooking. William was like, ‘You’re crazy!’ “
