The Duke and Duchess of Cambridge, Prince William and Kate Middleton, disembarked the HMCS Montreal in Quebec City this morning. Kate and William spent the night on the warship as it made its way on the St. Lawrence River from Montreal to Quebec City, where they came ashore today. William and Kate also attended an interdenominational church service, which was held on the deck of the ship in their honor. The royal newlyweds spent a short amount of time yesterday in Montreal, where Kate Middleton took a cooking class wearing a traditional chef uniform. Also on Saturday, Will and Kate planted a tree to symbolize their love in front of one of the many crowds who have gathered to get a glimpse at the couple. It's been an action-packed visit to Canada so far for William and Kate, and there's no slowing down yet. With about three outfits a day for the duchess, there's lots of talk about the beautiful dresses she's picked to wear, and FabSugar is keeping track of all Kate Middleton's Canadian fashion throughout the trip.

Beyoncé Knowles had a big smile on her face yesterday as she rehearsed for Macy's Fourth of July Fireworks Spectacular in NYC. Beyoncé had the Statue of Liberty right behind her for the trial run, which will be even more exciting when the fireworks show is going on as well tomorrow. It's been quite a week for Beyoncé, with the release of her album 4 and a big GMA Central Park performance on Friday morning. She also made a surprise appearance at Target in Harlem, where Beyoncé danced with kids to her new hit "Countdown." Beyoncé's July 4 special will air on NBC and features a performance from Brad Paisley as well.

Prince Harry was looking good atop a horse during the British Polo Day Charity Cup in Watership Down on Saturday. While his brother, Prince William, and Kate Middleton visit Canada, Harry is holding down the fort at home in England. On Friday Prince Harry attended the Wireless Festival in Hyde Park with his cousin Zara Phillips. Prince Harry didn't bring a romantic date along for either the polo match or the festival, though he is rumored to have a new lady in his life. He split yet again from Chelsy Davy and weathered another round of reports about his relationship with Pippa Middleton, but the most recent stories say that Prince Harry is seeing model Florence Brudenell-Bruce.

Brad Pitt had two special visitors, his sons Maddox and Pax Jolie-Pitt, on the set of World War Z in Malta Saturday. Pax looked superstylish in his skinny jeans while Brad Pitt was once again in his World War Z scarf, cargo pants, and navy shirt, which at this points seems to be his one and only outfit for the zombie film. The Jolie-Pitts may be missing out on the July 4 festivities stateside, but they're still getting in the spirit of Summer overseas. Angelina Jolie wore a wetsuit for a family trip to a local water park last Monday, and she was also spotted bringing the six kids out bowling later in the week.

Kristen Stewart mounted a horse in Palm Springs Friday. She was decked out in her usual tee and jeans outfit but also sported a helmet and riding boots. It appears the actress is prepping for her role in Snow White and the Huntsman, which will have the star atop a horse for filming. Kristen's been staying in shape with regular workout sessions all week, and she was most recently spotted leaving a yoga class in LA on Thursday. The equestrian fun ended since Kristen was back in Beverly Hills Saturday, and she threw on cutoff shorts to take care of some errands. Kristen was greeted with a parking ticket, though, when she arrived back at her Mini Cooper.

Good friends Zac Efron and Ashley Tisdale played together on the beach in Malibu, CA, Saturday. It was Ashley's 26th birthday, which she celebrated by basking in the sunshine sporting a sexy bikini with her pals, including High School Musical costar Zac. The two have been close for years, though Ashley's BFF and Zac's ex, Vanessa Hudgens, wasn't spotted partaking in the party. Ashley did get a piggyback ride from muscle-bound Zac, who showed off his shirtless physique. Zac Efron also supported Ashley Tisdale at the premiere of her latest DVD release earlier in the Spring, and they both had downtime to enjoy the long holiday weekend and the big two-six for Ashley.

Fashion icon Kate Middleton traded couture for culinary chic Saturday in Montreal. Kate and Prince William enjoyed a cooking workshop at the Institute of Tourism upon arrival in the Canadian city. The Duke and Duchess of Cambridge looked like they were having a blast during the demonstration, which came at the end of another very full day in Canada. Prince William and Kate participated in Canada Day celebrations on Friday night and were up bright and early yesterday to plant a symbolic tree of love in Ottawa before bidding farewell to the first stop on their North America tour. Today William and Kate are scheduled to meet with the Royal 22nd Regiment, who recently returned from a tour in Afghanistan, and then the royal newlyweds are off for a brief trip to Prince Edward Island on July 4.
