Going all out for her beau's special day, Ellie made turning 27 a memorable occasion for the McBusted guitarist.
Well, it's not every day you get one of London's top museums all to yourself!
Booking Dougie his own private tour of the Natural History Museum, the couple enjoyed a midnight stroll through the attraction's exhibits.
And, by the looks of things the birthday boy loved every minute.
Sharing a photo of himself and Ellie stood alongside a dinosaur skeleton, Dougie said: "I got the Natural History Museum for my birthday! Thank you to me luuuuvly lady @elliegoulding."
While they were there, Ellie also shared her surprise with her followers. Posting a picture from inside the museum, the 'Burn' singer said: "The Natural History Museum at midnight. Eerie when there's only two of you..."
She then went onto publicly wish her boyfriend a happy birthday. Alongside a photo of Dougie, she wrote: "Happy Birthday wonderful human being. There should be more people like you in the world. @idougahole."
The couple's trip to the museum come after Dougie recently denied he and Ellie were engaged.
Fans questioned whether the pair were set to wed after noticing a ring on Ellie's engagement finger.
But, quickly dismissing the rumours, Dougie denied that was the case, stating the ring Ellie was wearing just happened to fit that finger.
Even though wedding bells may not be right around the corner, both Dougie and Ellie - who started dating back in May - seem very loved-up.
Earlier this month, Ellie told Capital FM "she just melts" when she hears Dougie sing.
Speaking about her other half, Ellie cutely said that she loves Dougie's voice and wished he sang more on McBusted tracks.
"He has got a really amazing voice," she gushed. "His voice literally makes me melt, and he doesn't believe me! When he sings I just, like, collapse. I love his voice so much."
