aking a royal entrance befitting of her rock star lineage, Georgia May Jagger rode up in a vintage Porsche Speedster Tribute 356 flanked by motorcyclists to the launch party of her new collaborative line with fashion brand Volcom.

Last year, the 25-year-old model and London native, daughter of Mick Jagger and Jerry Hall, became an ambassador for the Costa Mesa-based surf, snowboard and skater-oriented label bought in 2011 by French luxury conglomerate Kering. Their new 15-piece Volcom X GMJ line ($32-$101.50 at www.volcom.com) includes T-shirts, a hoodie sweatshirt, scuba-inspired swimsuits, slender cigarette pants, a military jacket, a perforated bomber jacket, and star-patterned rompers and shorts.
