Geike Arnaert (born 13 September 1979) is a Belgian singer, best known for being the lead vocalist of the band Hooverphonic from 1997 until 2008 and again since 2020. Geike was born in Poperinge and grew up in Westouter, a town that is close to the French border. From a young age she was captivated by music and therefore she decided to audition for the Belgian band Hooverphonic, the group of guitarist Raymond Geerts and Alex Callier.
Geike's first hit succeeds with luster and is preferred to the other auditors. And although the band climbs many festival stage, it takes until 2000 before Hooverphonic scores a hit in the Flemish Ultratop 50. With Mad About You the group was 14 weeks in the charts, with number 23 being the highest position. The album The Magnificent Tree, which contained Mad About You, peaked second in Flemish Ultratop 200 Albums chart, third in Walloon Ultratop 200 Albums chart, as well as 25th in Italian album chart.
