McQueen's father, Ronald, and his five siblings were also among the 100 or so mourners at the late fashion designer's private funeral in London.
The service came two weeks after the designer was found dead at age 40. A coroner's report released last week said McQueen hanged himself after leaving a note behind. In the days leading up to his death, McQueen had tweeted several times about grief over his mother, Joyce, who died Feb. 2.
A memorial service for friends and supporters will take place sometime later this year, according to People. Paris fashion week will pay tribute to McQueen on March 9.
