Exclusive New Couple Alert: Jared Leto and Shia LaBeouf's Ex

From A-list babes like Cameron Diaz and Scarlett Johansson, Jared Leto is now dating a notorious D-lister, Isabel Lucas RadarOnline.Com has exclusively confirmed. If sloppy thirds wins the jackpot, then Jared Leto has stepped in gold. Seemingly climbing the Hollywood stardom ladder, Isabella has traded up from Adrien Grenier to Shia Labouf and now onto hunky Leto in the past six months!

Last night the Leto/Lucas duo was hanging at the swanky Chateau Marmont in West Hollywood with some "rocker looking friends." A source reveals to RadarOnline.com, "the duo only paid attention to each other!"

Three big stars in six months time for the Australian temptress Isabella. There must be something going on down under. (Photo: Splash News Online)
