Rodriguez/Getty Images Ashlee Simpson has kept a low profile since giving birth to her baby daughter, Jagger Snow Ross, back in July. But on Tuesday night in Los Angeles, the “Pieces of Me” singer and husband Evan Ross took a well-deserved break from their diaper duties to celebrate the launch of Guitar Hero Live in ultimate Southern California style. Ross sported a rock star–like look that included a sheer black and white polka-dot shirt with matching black skinny jeans, sharp camel ankle boots, and a matching blazer. Also not to be missed: his oversize, rounded hat. Meanwhile, Simpson showcased her figure in a black dress with matching patent leather pumps and a statement-making, oversize blazer that spoke to her experimental style. The orange-hued piece included patchwork detailing and was adorned with a smart, artful graphic pattern. She wore her hair in a slicked-back ponytail that highlighted the glow of her complexion. So how did the happy parents spend their time off together? “Played @guitarhero with my baby @realevanross tonight!” she wrote in an Instagram snap of them on the red carpet. “We had fun checking out the new #Guitarherolive.” PHOTOS: Ashlee Simpson's Changing Looks We can’t wait to see the entire family step out in full force.
