Brad Pitt had his iPhone in hand today as he took a private tour of the Documenta 13 art exhibition in Kassel, Germany. The Documenta event is held once every five years, and Brad, who is a well-known appreciator of art and architecture, stopped by to check out the newest installation during his stay in Europe. Earlier this week, Brad indulged in another one of his passions when he stopped by a Honda motorcycle shop in London. Angelina Jolie is currently filming Disney's Malificent there, and Brad and Angelina are staying in a $16 million home in the Richmond section of the city during their stay in England. Meanwhile, Brad will be completing some unexpected work of his own in the coming months. It was just announced that his zombie film, World War Z, is going through a rewrite that will require new footage to be filmed and potentially change the ending of the movie. Reshoots are expected to begin in September.

Suri Cruise and Katie Holmes stopped by Jacques Torres Chocolatier today in NYC. Suri clutched a cupcake in one hand and her stuffed panda in the other as she arrived at the sweets store with Katie. The mother and daughter browsed together, and Katie sampled some of Jacques's creations while they shopped.

Suri and Katie reunited with Tom Cruise in their homebase of the Big Apple earlier this week after a month full of travel for the family. Tom was given the Entertainment Icon Award at the Friars Club on Tuesday night and had Katie, Suri, and his son, Connor Cruise, by his side as he accepted the honor. Katie returned home just in time for the event after a weekend trip to Beijing, where she served as the ambassador and spokeswoman for the figure-skating event Artistry on Ice. Be sure to let us know how you think Katie and Tom's busy years compared to their fellow celebs in this year's PopSugar 100 faceoff!

Jennifer Lawrence was all smiles running errands around LA today. She stopped in at a salon for a bit of pampering, then headed on her way with freshly painted nails. It seems Jennifer decided to treat herself to a restful afternoon after enduring some rigorous training in recent days. Jennifer's back to her intense workout routines as she prepares to resume her role as Katniss Everdeen in The Hunger Games sequel.

While Jennifer's hanging on the West Coast, her big-screen costar Liam Hemsworth is currently shooting Empire State in New Orleans. There have been some big changes in his personal life recently with news of his engagement to Miley Cyrus. Miley visited him on the set last week, and it's possible she'll be dropping by the set of Catching Fire this Fall to see her fiancé, Jennifer, and the rest of the cast. If you're a big Hunger Games fan, make sure to vote for Liam and Jennifer in the PopSugar 100 before the contest ends this weekend.

Miley Cyrus left her Miami hotel today with her friend Cheyne Thomas, who carried her luggage to the car. Yesterday, Miley wore a white bikini while relaxing at a pool with Cheyne. It wasn't all fun, though, since just-engaged Miley had to defend herself on Twitter in response to the buzz about her spending time with another guy. Just before her Miami getaway, 19-year-old Miley saw her fiancé, Liam Hemsworth, in New Orleans, where he is filming Empire State.

If you're a Miley or Liam fan, then make sure to show them some love in the PopSugar 100 before the contest ends this weekend.
