The singer had a long-running feud with the two brothers which began in the mid-90s and escalated to a point where Robbie challenged Liam to have a boxing match with a £100,000 (S$160,500) bet on the line at the BRIT Awards in 2000.

Although Robbie appeared to be a willing participant in the slanging match, he has now claimed that the pair's comments, which many of his musical peers seemed to agree with at the time, left him depressed and ultimately inspired him to quit Britain to move to Los Angeles in 2004.
