Vector boson+jets as background to top-quark physics at Tevatron and LHC

Abstract

I review here the latest measurements related to vector boson production in association with light or heavy flavor jets at the Tevatron and at the LHC. The methods to estimate the W+jets and Z+jets background in top-quark analyses are also presented.
