Zachary and Elijah are growing up fast
The boys are with their fathers in America as Elton continues his farewell tour, and they were surprise guests at the Elton John Aids Foundation Oscars Viewing party, where they were welcomed on stage by David and their godmother, Lady Gaga.
David told HELLO! on the red carpet that Zachary and Elijah had offered to help host the show when the family realised Elton would be on tour.

"They heard us talking - we had planned for Elton to be off the road in February but then they moved the Oscars to March, and fans had been holding on to tickets for 700+ days and we knew we couldn't keep moving shows," David said.
"So the boys said, 'we will help you.' I am really proud of them."
