Today the world is celebrating Robert Pattinson's 27th birthday.

But how exactly will the birthday boy and girlfriend Kristen Stewart make this day extra special?

A source tells E! News exclusively the couple will have a big get-together with friends—including, possibly, Katy Perry!—at Kristen's Los Feliz, Calif., home.

From there Rob, K.Stew and their pals will probably go out, says the source.

We certainly hope R.Pattz has a blast as he rings in the big 2-7!

And hey, we don't have any plans tonight. Just sayin'...
