Joel Madden returned home from a trip to Sydney yesterday and soon went out on a couple's shopping trip in LA with his Vanessa Bruno-clad wife, Nicole Richie. The pair stopped by Lindy & Grundy's butchers, then paid a visit to The Commissary for coffee. Joel may have needed the caffeine after his 72-hour trip to Oz, where he and his brother Benji presented at the ARIA awards. The Good Charlotte singer might be spending more time Down Under in the coming months since Joel's mentoring on the Aussie version of The Voice with Keith Urban and Seal. Nicole is also doing her own work in front of the cameras in 2012, sharing the small screen with Jessica Simpson on Fashion Star.
