Katie Holmes took a break from filming The Kennedys for some quality time in Toronto with daughter Suri.

"They were looking in store windows and just enjoying the day," a source says.
In Chicago, Jennifer Love Hewitt danced the night away at Sub51 to DJ Spider's tunes after her late-night meal upstairs at Hub51 with friends. The next night, Scream 4 costars David Arquette and Neve Campbell were spotted dining (separately) while in town to enjoy the musical offerings at Lollapalooza.
Ashley Greene threw a pool party at Las Vegas's Wet Republic, where the Twilight star partied in a VIP bungalow with an entourage of over a dozen friends. She also flaunted her body in a blue bikini, lounging in the pool, taking Hpnotiq shots with fans and enjoying plenty of savory snacks like sliders.
