The pair, who tied the knot back in July, announced their happy news on social media earlier this month.
Olly and Amelia posted a sweet montage of clips from when they told their family and friends the happy news.
At the beginning of the clip Amelia can be seen handing Olly the pregnancy test – and he looks at her in shock.
In another video their loved ones are sitting in a home cinema when they are told that they are expecting.
They recorded loads of other reactions of them showing their friends and family the scan picture.
Olly and Amelia captioned the post: “It wasn’t just our hearts that skipped a beat.. 😱😮💛.”
Many rushed to the comments section to share how happy they are for the couple.
Mark Wright said: “This is beautiful.”
Denise Van Outen added: “Congratulations.”
Last week the pair shared a snap which Amelia showed off her growing belly, while Olly held up a scan and pointed at her bump.
They wrote: “Baby Murs due 2024.”
The two got married on the private Osea Island in Essex over the summer, after getting engaged in 2022.
Olly and Amelia met in 2019.
