(CNN) Paul McCartney isn't too shy to let everyone know the significance of June 18.
(Hint: It's his birthday.)
The singer shared a photo with a brief caption in honor of his 77th turn around the sun.
"It's my birthday too, yeah," he said.
And everyone from Yoko Ono, a former wife of his bandmate John Lennon, to the estate of George Harrison, the lead guitarist for the group, has shared their birthday wishes.
