And now you have the chance to meet the star as she pops into town for a special appearance at the MAC counter in Selfridges on London's Oxford Street on Thursday, December 11, 2008.
In her role as MAC Viva Glam spokesperson, the singer-songwriter will be signing MAC Viva Glam posters for fans between 1-2pm on the day, as well as meeting MAC fans. Anyone who has bought a MAC Viva Glam Lipstick, £10.77, or Lipglass, £10.28, from the counter between December 8 and 11 will receive a signed, limited edition poster and a pass to meet the superstar.
Fergie acts as a voice for the MAC AIDS Fund's Global Youth Prevention Initiative, which will benefit from all proceeds of sales of the new Viva Glam VI Lipglass and in turn fund global organisations addressing young people affected by the AIDS crisis. To date MAC has raised more than $130 million for the cause.
Previous celebrities to have supported the initiative include Christina Aguilera, Missy Elliott, Linda Evangelista, Chloe Sevigny, Elton John, Mary J Blige and L'il Kim.
