Nicole Richie was seen at the Roxy over the weekend with absolutely no signs of any baby weight on her!

Nicole took her little sister (and was accompanied by long-term love Joel Madden) to see the Selena Gomez concert. Looking at her in this little black outfit you would really never guess that she gave birth to son Sparrow less than a month ago!

Nicole took to Twitter after the show, saying ““Took my little sister to see @selenagomez 1st show; or she took me…”

I can’t believe how quickly Nicole lost the extra pregnancy pounds!
