Brad Pitt wore a big jacket this afternoon to work on World War Z near the beach on the south coast of England. He's been in the UK doing reshoots for the action film for the last few weeks. He and fiancée Angelina Jolie have gotten accustomed to being in England over the last few months, since she also shot Maleficent there. Their six kids are settled down there for the time being as well. It seems the location has allowed Brad and Angelina to catch up with some of their old British friends. Angelina hosted an event for Ewan McGregor, a Scot, in honor of what she's dubbed his "honest" performance in The Impossible. She organized a special screening to celebrate Ewan's work last Sunday at London's Soho Hotel.

Nicole Richie and Joel Madden accompanied their kids, Harlow and Sparrow, to the Yo Gabba Gabba! live show in LA yesterday. Nicole gave Sparrow a ride on her shoulders, as Joel followed close behind carrying Harlow in his arms. Also in attendance was Halle Berry and her daughter, Nahla Aubry. It has been quite a week for the mother-daughter duo. On Thanksgiving, Halle's ex and Nahla's dad Gabriel Aubry fought Olivier Martinez, Halle's fiancé, after words were exchanged when Gabriel dropped Nahla off for the holiday. Both men were treated at the hospital, and Gabriel was arrested. In contrast, it has been a relaxing week for Nicole. She hosted a Thanksgiving dinner at her home and, earlier this week, took a dressed-up Harlow to Bronx Wentz's birthday party.

Tom Cruise was on the set of All You Need Is Kill today in London's Trafalgar Square. Today, he was before the cameras today shooting in a helicopter. It was back to work for Tom following a quick break for Thanksgiving. Tom spent the holiday with Suri Cruise, his youngest child, who flew to the UK from her home base in NYC. Suri's mom, Katie Holmes, left the Big Apple for Thanksgiving, too, making a one-day trip home to see her Holmes relatives in Ohio. Suri went to England earlier this week to spend some quality time with her father, as well as her two siblings, Connor and Isabella Cruise. It was a sweet reunion for the Cruises, since Thanksgiving was the first time Tom had seen Suri in three months.

Ashton Kutcher and Mila Kunis went out to dinner in Rome last night. They ventured to the Trastevere neighborhood for a meal at Checchino Dal 1887 and seemed to have the whole place to themselves. Ashton even left with a decorative plate commemorating their visit. Ashton and Mila are enjoying an extended getaway together in Italy, where she's shooting The Third Person with director Paul Haggis and a long list of costars that includes Liam Neeson, Olivia Wilde, and James Franco. Ashton ventured to Europe to spend time with Mila when she's not on set, and they've been spotted sampling many of the city's traditional restaurants together.

Robert Pattinson and Kristen Stewart arrived at an airport in NYC together last night. They're back in the US after reportedly spending a few days in the UK. Rob and Kristen were due for a break — they've been on a whirlwind international press tour on behalf of Breaking Dawn Part 2, which topped the box office during the weekend following its Nov. 16 release.

The last two weeks saw Robert and Kristen, along with their costar Taylor Lautner, make stops in LA, Madrid, London, and Berlin. For her various red-carpet adventures, Kristen rocked an edgy, sexy style that's somewhat new for her. Kristen Stewart's stylist Tara Swennen explained Kristen's fashion evolution, saying Kristen's "grown into being more comfortable on the red carpet; she’s definitely embracing elegance and gracefulness."

This week brought us Thanksgiving, but that didn't mean stars had time off! They were busy hitting red carpets or logging time on set. Jennifer Garner got a visit from her little ones, Samuel and Seraphina, while making The Dallas Buyers Club in New Orleans, while Scarlett Johansson and Jessica Biel linked up with their Hitchcock costars, Helen Mirren and Toni Collette, at the NYC premiere. On the other hand, bikini-clad Courteney Cox showed off her fit physique while vacationing in Miami, and Justin Bieber and Selena Gomez reunited for a date night in LA.
