After counting down the days to her birthday in a semi-disturbing way (above), Courtney talked to E! online exclusively about her birthday and new dog:
"I received the most precious birthday gift from my hubby," Courtney says. "A little boy Italian Greyhound named Dourtney."
And when it comes to celebrating turning the big 1-8, Courtney plans on simply spending the day "with my loved ones, my new beautiful puppy and my incredible man."
As for what we can expect between now and when she hits that other big milestone—21—Courtney remains coy.
"There are quite a few secrets that we cannot tell you right now, but expect to see a lot!"
