Meghan Markle and Prince Harry are sending their well-wishes to their pal, Elton John. The duo joined forces with a long list of the British singer's famous friends to pay tribute to his historic career, as he played the final show of his Farewell Tour in North America at Dodgers stadium on Sunday. "Thank you for being the friend that you were for my mom. Thank you for being our friend. Thank you for being a friend to our kids," Harry said.
