“Huge congrats, Sir Ringo! Sir Richard Starkey has a nice ring to it," McCartney wrote on Instagram. "Best drummer, best pal! X Paul.”
Meanwhile, John Lennon's widow Ono added that the honor was a long time coming for Starr.
"Huge congratulations!" she wrote via Twitter. "I am delighted for you and your family. It is an honour for everyone in The Beatles family and I love you very much.
For his part, the drummer was thrilled at the distinction.
"It's great," Starr said. "It's an honor and a pleasure to be considered and acknowledged for my music and my charity work, both of which I love. Peace and love."
Starr was honored for "services to music."
McCartney was knighted for the same reason in 1997.
