The former Celebrity Big Brother star announced yesterday that she and Doug had patched up their differences and want to be together again.
She tweeted: "Thank you everyone for all your sweet congratulations msgs, love & support! It means so much #kudos2love."
Courtney, 19, and Doug, 54, split in November, shortly after Courtney's time in the Celebrity Big Brother house, although they continued to remain friends and Doug stayed on as her co-manager.
She told Reveal in May: "Doug and I are definitely separated. What's been great about our separation, though, is that we remain close friends and desire nothing but the very best for each other. I'm so proud of that."
"We, honestly, are the best of friends now. I can talk to him about anything and everything. I'm eternally grateful for meeting him and I have zero regrets. As far as Doug co-managing me, we still work closely together on business affairs. Also, I'm on the verge of some acting endeavours and Doug is helping me along with my acting abilities."
Fast-forward two months and romance is in the air again!
Courtney's mum Krista Keller broke the news to FOX411, saying: "Courtney realised just how much love she really had for Doug. They really love each other and wanted to be together."
The couple's relationship has hit headlines since the beginning. They met via an online acting course that Doug was running and romance blossomed over the internet. They married in Las Vegas when Courtney was 16 and Doug was 51 – with Courtney's parents' blessing.
It's believed their split in November was prompted by Courtney's time in the CBB house, as she later said the experience allowed her to grow as a person.
"I thought it would be a great experience and I do feel I've grown into a woman now. When I came into the house I was only 18. I have learned so much, gained so much. I didn't realise I was that strong to be in that house for three weeks. I feel more like a woman and I'm glad this was my first time out of the country. It was a great experience and I'll never forget it."
