Less than a month after Lauren Conrad welcomed her first child, another The Hills star has become a mum.

Whitney Port and husband Tim Rosenman announced the birth of their son on Monday, revealing they named their first child Sonny.

“I made a human!” Port, 32, wrote on Instagram.

“Sonny Sanford Rosenman was born on 7/27/17! Everyone is so happy and healthy and we are home now.”

Elaborating on her blog, the reality star turned fashion designer said she experienced feelings she never had before when “the doctor placed Sonny onto my chest.”

“I love him and feel protective over him, but more than anything, I’m just like obsessed. I can’t stop looking at him, or thinking about him when I am in another room.”

“I can’t wait to watch him change and grow and take on my traits and Timmy’s,” she gushed.

Port’s news comes just weeks after Lauren Conrad and husband William Tell announced the birth of their first child, a son name Liam, earlier this month.

And yet another former The Hills star will give birth this year: Heidi Montag and Spencer Pratt are due to welcome their first child in October.

Congratulations, Whitney.
