Only M.I.A. and her little bump in the oven could upstage Jay-Z, Kanye West, Lil Wayne and T.I. during their 2009 “Swagga Like Us.” A very pregnant M.I.A. performed alongside the Rap Pack, in a see-thru dress at that. Fans at home cringed, hoping that little M.I.A. Jr. would not make his stage debut during the song.
