As they brought an end to the first day of their North American tour, Prince William and Kate Middleton attended an informal reception for young Canadian volunteers in the official residence of the Governor General of Canada in Ottawa on Thursday night (June 30).

The Duke and Duchess of Cambridge took to Rideau Hall with Kate wearing her third dress of the day, this time looking adorable in a black and white Issa wrap frock with wedge sandals.

Despite the overseas travels and time spent with Canadian Prime Minister Stephen Harper and his wife Laureen during a wreath laying ceremony at the National War Memorial, Miss Middleton was in fine form.

Asked by an attendee if she and Will were worn out from the hectic afternoon, Kate replied, “We are fine, not too bad.”

Meanwhile, the royal couple are all set to join millions of Canadians to take part in tomorrow’s Canada Day celebrations - which mark Canada’s 144th Birthday

There’s nothing like a great summer comedy, and “Horrible Bosses” brought the laughs at its Los Angeles premiere tonight (June 30).

Big names like Jennifer Aniston and Jason Bateman showed up at Grauman’s Chinese Theatre to promote the flick, due to hit theaters on July 8th.

Also in the house were fellow castmates including Jamie Foxx, Julie Bowen, Jason Sudeikis and the lovely Lindsay Sloane.

Meanwhile, a handful of Tinseltown stars were also in attendance at the red carpet event, as Jennifer Love Hewitt, a pregnant Alyssa Milano, Jenna Elfman and Chelsea Handler all made appearances.

As for the Seth Gordon directed film, “Horrible Bosses” is about “three friends who conspire to murder their awful bosses when they realize they are standing in the way of their happiness.”

She’s no stranger to red carpet affairs, and earlier tonight (June 30) Jennifer Aniston made her big arrival at the Los Angeles premiere of her new movie “Horrible Bosses.”

The “He’s Just Not That Into You” actress was looking mighty fine in a stylish black frock as she hammed it up for the shutterbugs outside Grauman’s Chinese Theatre.

And according to a FOX Pop Tarts source, Jen has been exhibiting some very Angelina Jolie-like tendencies as of late, including getting a tattoo and stealing her new boyfriend Justin Theroux out of a 14-year relationship.

“Jennifer Aniston definitely seems to be taking a page out of the Angelina Jolie book! She’s savvy and she knows what people want to see from her. She just wanted Justin no matter what and went after him. It seems like she doesn’t care about the fact that he had a girlfriend. He might have told her they were broken up but Heidi didn’t seem to know. Jen once said Brad was missing a sensitivity chip but it seems like she’s the one now who is missing the sensitivity chip.”

Dr. Patrick Wanis, a human behavior expert agrees. “Jennifer may be subconsciously modeling and matching Angelina because she sees that Angelina has what Jennifer always wanted – stability in love, success on and off screen and meaningful goals that unite and deepen the bonds between Angelina and Brad.”

Straying from her typically clean and family-friendly persona, Gwyneth Paltrow is stripping down for the upcoming issue of Vanity Fair.

The 38-year-old actress tossed off her top while donning only a pair of black fishnet tights and Louis Vuitton baubles for a special jewelry supplement in the magazine’s August issue.

Meanwhile, Miss Paltrow also made headlines today after taking the stage for a special guest appearance with the cast of “Glee” during their live show at London’s O2 Arena on Wednesday night (June 29).

Recently opening up to Vanity Fair about being followed by paparazzi now that her stardom has risen, Emma recounted a story involving one of the constantly present shutterbugs.

She told, “(The paparazzo) stands up while I’m walking to my car and is like, ‘Hey, Emma! Listen, I’m going to delete these pics. Here’s my card.” She continued, “If you ever go to the beach with your friends or walk out of your house in your pajamas, call me.’”

Not wanting to buddy up with the camera-toting businessman, Miss Stone then said, “He’s like, ‘But I’m deleting these pictures, see?’ These guys try to strike up a deal with you so you feel like they’re your friend. I didn’t even know that was a thing—that people would call them.”
