Who knows how well they actually get along, but the Ronson kids certainly have the makings of a legitimate sibling rivalry.  Mark is a Grammy Award winner and has worked with countless high-profile musicians, while Samantha is among the most famous DJs in today’s club scene.  Little sis probably has DJ Mark beat in terms of noteriety, given her exposure with Linsey Lohan, but Mark wins this round in terms of pure luxury.  Sure, Sammie’s Supras are dope, but few brands can match Gucci when it comes to high-end steez.  The Gucci Icon pop-up stores will feature Mark Ronson’s sneaker designs among others.  The prices range from $500-1400 with ‘the Ronsons’ topping out at $600.  Take a look at the photos after the jump and let us know if that’s a fair price.  via WWD
