Yikes. Even though Robbie looks a bit like distressed leather these days, he’s still on point when it comes to performing. At Mark Ronson’s first-ever performance as a headlining act in Los Angeles, he welcomed the British pop star to the stage to accompany him on their take on The Charlatans’ song, “The Only One I Know.” In addition to receiving on stage support from Williams, Ronson also was joined by Nikka Costa, rapper Tiggers, as well as a number of other artists, all of whom lent their musical talents to the sold-out show at the El Rey Theatre. Nicole Richie and baby-daddy, Joel Madden were some of the audience who showed up to enjoy the musical stylings of Ronson and company. Shouldn’t she be in bed? Mostly, I’m saying that because it looks like she just woke up. Well, enjoy it now, Nic, cause soon, you’ll have a screaming baby waking you up at all hours of the night. Oh wait, you’re rich. You’ll just buy a nanny to do all the dirty work. I never win.
