They’re both big fans of promotional appearances, and last night (May 6) Nicole Richie and Joel Madden were spotted at the launch of the House of Harlow 1960 Jewelry Collection in Miami, Florida.

The “Simple Life” hottie and her “I Don’t Wanna Be in Love” rocker beau looked to be having a wonderful time as they mingled with fellow guests at Ida and Harry at Fontainebleau.

Mr. Madden looked a little extra punky as he sported his new bleached-blonde coif along with aviator sunglasses and a pair of gold chains.

Meanwhile, Nicole was beaming with pride as she showed off her House of Harlow wares, sporting a vintage turquoise floor-length silk dress with gold bangle bracelets and armbands.
