Jake: Bachelor on the Prowl

What is up with Jake Gyllenhaal and the ladies? One weekend, you hear about him and Lindsay. The last couple of weeks, it's a new girl on his arm constantly...

The girl on the right, in the long-sleeve shirt at the table appears to be the same chick who was out walking with him over the weekend...anyone know who she and today's apparent flavor of the day are?

UPDATE: Apparently, the tall, beautiful blonde is a longtime friend of Jake's who grew up with him in L.A. So ladies, it sounds like he's still not officially taken.
