Keira Knightley Happy to Go Nude on Film

Keira Knightley has no problem appearing in the buff for her latest film. In fact, she says it's becoming a habit.

"I always bare my breasts," she said at the press conference to promote The Edge of Love Wednesday at the Edinburgh International Film Festival. "It's not like it's only in this film!"

The British actress, 23, is best known for the Pirates of the Caribbean films; last year she went au naturale in the period drama Atonement.

Referring to a scene in the wartime romance The Edge of Love with her onscreen husband Cillian Murphy, Knightley said: "It was very simple. It was a sex scene and I never like them when they've got bras on."

So when the director asked her to remove her bra, "I said, 'All right then.'"

But when it came to her singing scenes, the British actress needed much more persuasion. On hearing she had to sing live in front of the cast and 100 extras, she said, "I thought I was going to die. My knees actually started buckling."

The film was written by Sharman Macdonald, Knightley's mother, who says her actress daughter was the inspiration for writing the period romance that also stars Sienna Miller, 26, and Matthew Rhys (Brothers and Sisters.)

"I wasn't particularly pleased that Shar put singing into the script – in the first couple of takes I sounded like a apubescent boy," says Knightley, who calls her mom Shar and instead of mother.

At the film's premiere in Scotland on Wednesday, Knightley (in a cream Chanel jumpsuit) and Miller (in a Jasmine de Milo dress) walked the red carpet holding hands.

The two fashionable costars "are incredibly warm in the film and that's the way they are in life," says mom Macdonald. "They knew each other slightly before and then they just completely bonded on the film. I hope they will be friends for life!"

Audrina Joins Lauren to Celebrate Lo’s Graduation

Lauren ‘Lo’ Bosworth and roommates Lauren Conrad and Audrina Patridge (who had recently been feuding with best friends) along with Spencer Pratt’s sister Stephanie ate at West Hollywood sushi restaurant Kumo before heading to the Green Door lounge in Hollywood to celebrate Lo’s graduation from UCLA — and to film and episode of The Hills.

Arriving just after 9 p.m., Lo, Lauren and Audrina all walked in the restaurant together laughing and headed straight for their booth in the back of the restaurant, which was decked out with cameras on tripods, of course.

Lo (with her hair done and in a short silver backless dress) was the center of attention sitting right in the middle of her roomates. “They all seemed to get along fine,” says an onlooker. “At the beginning of dinner Audrina was a little out of it but she settled in and all the girls were talking together, having a fun time.”

Arriving solo, Stephanie Pratt in a bright orange mini-dress walked in carrying a bouquet of flowers. “She walked right up to the table and gave Lo the flowers and gave her a hug. Lo was genuinely happy and really sweet to her.” Once Pratt arrived, everyone toasted to Lo with glasses of champagne.

The crew (plus two of Lo’s unidentified friends) dined for about two hours, chatting, occasionally making bathroom trips and all really getting along. “Steph and Audrina talked a lot of the time but Stephanie was the one who was out of the group the most, on her Blackberry a lot. Still, everyone was having a good time with each other … things didn’t seem weird.”

Conrad sipped a martini and the group went through rounds of signature sushi dishes. They headed out around 11 p.m., laughing and giggling on their way to the Green Door, where they met up with Brody Jenner and wingman Frankie Delgado. Lauren and Audrina were spotted chatting in their booth in what turned out to be (shocking!) free of drama.

Fergie Stays Mum on Wedding Plans

She was proudly flashing her engagement ring at the third annual Cartier Loveday celebration in L.A. on Wednesday, but Fergie remained coy about her wedding plans.

Asked about the best jewelry her fiancé, actor Josh Duhamel, has given her, she pointed to her engagement ring. "Well this one," she told PEOPLE. "This one is by Duhamel, it's a special stone and that's the most amazing one because it means something."

As for her wedding plans, "I can't talk about it," says the singer, 33, who announced her engagement last December. "I know I have a big mouth, but I can't say. That's the one thing that I have to hold private."

The pop star, who sings "Labels or Love" on the Sex and the City movie soundtrack, has both in her life right now. "I'm designing a new line of shoes so I'm excited about that," she says. "We're working on logos now, I'm really thrilled about that."

And she has plans for a follow-up to her smash solo debut, The Dutchess. What's next? "Getting in the studio," she says, "making new music."

Friends and Family: Jamie Lynn Will Be a 'Great Mom'

Jamie Lynn Spears's hometown of Kentwood, La., was buzzing with the news she gave birth, with friends and relatives expressing surprise, relief and confidence the 17-year-old will be a good mother.

"She's awfully young to be a momma," says distant cousin Margie Busby. "But that's what they make [grandmothers] for. They have to help. That's the way it is with our circle of friends."

Second cousin Janet Bridges acknowledges, "I didn't even know she had the baby," but gives a thumbs up to the baby girl's name. "Ooh, I like 'Maddie,'" says Bridges.

The birth was the talk of Kentwood. "I'm really happy for her and her family," says Jennifer Pike, who works at the corner store where the Spears family often shops. "There will probably be some rough times and some bumpy times, but I wish the best for her. I wish her all the luck in the world."

"We're so excited for her," a family friend tells PEOPLE. "She'll be a great mom. She'll be awesome."

Adds another friend, "She was so excited about having this child. (She was) looking forward to it so much."

The days have passed slowly for Spears and fiancé Casey Aldridge, who had finished preparing for the baby a few weeks ago. "It seemed like this day would never come," says a cousin of Aldridge. "They've been getting ready, but everything was pretty much done by last month. So they just had to wait."

Now that Maddie Briann is here, family members hope that Spears and Aldridge are good parents. "It's easy to have them, but hard to raise them," says relative Charlie Spears. "I hope she's healthy, and I hope they raise a good baby."
