Robert Peter "Robbie" Williams is an English singer and song writer. Robbie originally rose to fame in the early 90's when he was a member of the pop group Take That but in 1995 left the band to launch a hugely successful solo career, which saw his first seven albums each reach number one in the UK. In July 2010, he rejoined Take That.
The group's subsequent album 'Progress' became the second fastest-selling album in UK chart history. Robbie then left the band again but it is well known the door is always open if he ever wished to re-join.
