Beyoncé turned 40 Saturday and the internet is in a frenzy sending her heartfelt birthday wishes.

'The icon turns 40 today and to celebrate, BAZAAR enlisted the help of some special friends and fans,' the publication captioned underneath the Instagram post dedicated to the popstar. 

The video opens with an orange sweater-clad Oprah saying, 'Hello Miss B!' before Reese Witherspoon appears to sweetly say, 'Happy birthday, Bey!'

The star-studded video continues with Allyson Felix, Maya Rudolph, and Sesame Street puppet Miss Piggy joining in with a funny message: 'I'm so happy to see you on the cover of Harper's BAZAAR after I turned it down!' 

Viewers even get to see Stevie Wonder wish the queen a happy b-day from behind a drumset.
