Louise also shared another tweet with fans, revealing all she has ever wanted is to become a mother.
She tweeted: "I'm so happy right now! To be a Mum and start a family that's all I've ever wanted. Family means everything to me. #mummytobe."
The couple have since opened up about their baby news to Daily Mail, insisting that they are "over the moon" to be starting a family together.
Louise and Stu gushed: "We're over the moon to announce that we're having a baby. After being best friends for years then finally getting together, we're delighted to now become a little family.
"How exciting to go into 2017 knowing in advance it's definitely going to be the best year of our lives."

Stu was first to star on Big Brother, and appeared as a housemate back in 2008 on the show's ninth series. He was the ninth housemate to be evicted and later made an appearance on Ultimate Big Brother in 2010.
Louise, meanwhile, entered the house in 2011 for Big Brother's twelfth series and its first on Channel 5. She made it to the series' final and finished in fourth place.
Louise went on to marry her housemate Jay McKray in June 2012, but the pair divorced a year after tying the knot.
