Yesterday Steven Tyler turned 73, and Elton was among those sending the Aerosmith singer good wishes.
On Instagram, he posted a photo of himself with his colleague, adding: ''The kindest man with the biggest heart. A great support of EJAF for many years.''
Bernie Taupin also displayed a picture of himself with the performer.
He wrote: ''Happy birthday, Steven. Your exuberance is infectious. Rock on down the highway.''
And Joe Perry, his friend and bandmate, tweeted, ''From the first song to the last! Happy birthday to my brother in arms, Mr. Steven Tyler! Love you man!''
