Taking to her Instagram page on Friday afternoon, Audrina, 30, shared a snap of her Clearblue pregnancy test as well as this heartfelt message:

“I finally figured out what to get Corey for Christmas! #babyontheway #Clearblueconfirmed #ad (blog post with all the details will be up today!) xoxo."

And from the sounds of things, not only is the former Hills star with child – she’s signed up to be the face of pregnancy test company Clearblue too.

Is there anything these reality stars WON’T make money out of? Answer: absolutely not.

Patridge, who rose to fame as one of the faces of reality series The Hills, confirmed to Us Weekly that she was having her first child, telling them: “at this point in my life I am ready to be a mama!”

The couple got engaged just four weeks ago after eight years of on and off dating, with Corey popping the question over a romantic dinner.

And now they’ve got a little one on the way, we’re sure Corey and Audrina will be celebrating extra hard this Christmas (though without the booze, ey Aud?)

Congratulations to the happy couple!
