struck out for a night of bowling and romance with beau Brody Jenner
at New York's Lucky Strike Lanes
. The lovebirds
attended the launch for Picksie 2.0, an app that recommends hotspots in various cities. The two mingled with fans at the event but also hit the lanes ,where Jenner bested his girlfriend, bowling a 100, while Lavigne scored 88. And her bowling ball of choice? It was leopard-print.
