..And she couldn't be more embarrassed!
Hopping up on stage to collect the Teen Choice Award for her band, Selena Gomez had a bit of a surprise when she was also presented with a huge, flaming cake before being seranaded by the whole auditorium.
Collecting the award on behalf of her band, Selena Gomez and the Scene, she was rather embarrassed when everyone, including her good pal Taylor Swift, burst into song to help her celebrate her 20th birthday.
"This is the best birthday present ever," Sel said as she collected her surfboard, before being surprised with the cake.
We couldn't help wondering where boyfriend Justin Bieber was at this moment though - surely he should have had some sort of moonwalk or acapella to add to proceedings?
Chek out the video of Selena going bright red in the face for yourself..
What do you think of that then? Would you love that kind of surprise or would you be burying your face in your hands?
