There seems to be a lot going on in Europe this summer, because we've seen so many celebs hanging out on the old continent lately! Reese Witherspoon looked ultra chic while walking around Paris, while Vince Vaughn went the more casual route as he was spotted biking in Venice.

UPDATE: Reese met up with Jake Gyllenhaal after strolling along. I've added his shots to the picture gallery below. Click on each thumbnail to enlarge.  And Vince is actually in Venice Beach, not Venice Italy.  Thanks guys. :)
