A British TV anchor was left mortified after asking Bee Gees legend Robin Gibb if his brother Maurice was watching the interview - despite the singer passing away seven years ago.

Sky news presenter Steve Dixon was quizzing Robin about his twin's affair with British actress Barbara Windsor on Friday evening - the night before she was set to reveal all about her life in an interview with "America's Got Talent" judge Piers Morgan on U.K. TV.

After asking Robin Gibb about his brother's affair, he quipped, "Is Maurice watching this now?"

An embarrassed Gibb quickly advised Dixon that his brother had died in 2003, to which the red-faced reporter apologized adding that he was confused as there were "so many" Gibb brothers.

A spokesperson for Sky, "These things happen on live TV."
