The singer's latest album, The Heavy Entertainment Show, has debuted at number one on this week's chart.
It is his 12th album to reach the summit - and pushes him ahead of David Bowie, who has 11 number one albums to his name.
Williams said: "I'm chuffed that this album is number one and I'm humbled by these amazing statistics and facts."
The singer now has as many number one albums as Madonna, but remains behind The Beatles, (who have 15), and Elvis Presley (13).
