Louise is expecting her first child with fellow Big Brother star Stuart Pilkington and she cannot wait until she starts showing.
Sharing a series of pictures taken once she reached 15 weeks, Louise told fans how she is now keen to watch her body grow, adding that she is feeling in tip-top health.
She told her instagram followers: "15 weeks pregnant today and I know I'm still so tiny....I want my bump so bad!!"
Louise added: "The good thing is I'm finally feeling like myself, I have more energy and I'm eating a lot better which is good. Just over a week to go till I find out the sex of my baby...so excited, so happy."
Last month, Louise and Stuart announced their baby news, telling fans: "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."
Although the couple both appeared on Big Brother, they did not feature in the same series.
Stuart was first to star on the reality show, appearing as a housemate back in 2008. He was the ninth contestant 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 12th series and its first on Channel 5. She eventually finished in fourth place.
In June 2012, Louise married her housemate Jay McKray, but the pair divorced a year after tying the knot.
