Liam Payne sings happy birthday to Sophia Smith

And now our eye make-up is completely ruined. Thanks a lot guys.

Liam Payne sings Happy Birthday to Sophia Smith

From canoodling (yeah we said canoodling) in Monaco to attending glitzy events together, there's no denying that Liam Payne and Sophia Smith are one of our favourite couples to have ever walked the planet. I mean, is our obsession getting out of hand? Probs. All we know for sure is the latest footage of Liam singing Happy Birthday to her makes us feel all delicious inside.

Although the clip was filmed back in February while the two were on holiday in Sydney, it's only recently been leaked (again, thanking you, internet).

The video may be grainy but the message is loud and clear: Sophiam are too cute for words.

On a side note, is that a dog-shaped cake?

We're dying a little bt on the inside that 1) we weren't invited, and 2) we don't have a boyfriend like Liam.
