The former TOWIE star was clearly feeling all loved up as he shared his thoughts with fans via Instagram in a Friday evening (15 May) post.
Dan said: "My lady is THE most beautiful human I have ever seen! Sounds cringe but true.. What really counts though is that she is the most beautiful person inside too!! I am one lucky man! #soppymoment."
Fans were quick to respond with complimentary messages, with one fellow user saying: "Good for you for expressing how you feel! Not enough men do that!"
Another advised: "Don't let her go mate. When you find that one hold on to her."
Dan, 23, and Jacqueline, 22, are parents to baby daughter Ella, who was born in February 2015. Jac's currently on maternity leave from EastEnders, where she plays Lauren Branning.
Meanwhile, since exiting TOWIE earlier this year, Dan has been focusing on his role with The Dreamboys and spending time with his children. He's also dad to son Teddy, 17 months, from a previous relationship.
Followers of his social media feed will know he frequently shares snaps of his kids with captions expressing how proud he is to be a father.
