"I'll be taking a little bit of a step back from the site over the next few weeks as we adjust to life as a family of three (five, if you count Chloe and Fitz of course...).
"But not to worry ... my editorial team will be working hard to bring you tons of great content in the meantime, and I'll still be blogging here and there when I can, bringing you updates from my life as a new mom."
The couple married in September 2014 and Conrad announced her pregnancy on January 1 2017.
She is not the only member of The Hills cast preparing for motherhood - her co-stars Heidi Montag and Whitney Port are also pregnant.
