Nicole and Joel did some hand-holding shopping at Barneys in LA over the weekend. These two would have been a much cuter couple if they brought along baby Harlow. Now that Scarlett and Ryan are engaged, we wonder how much longer it will be until Nicole and Joel make it official. The couple sparked ring rumors before Harlow was born and now their rep denies it however, if Benji Madden is already talking about marriage, it might be time for Joel to take a hint from his twin brother.
