While the plot’s action probably kept him warm as - in character as Dr Watson - he raced around the Liverpool set in a lightweight period suit, between takes the 35-year-old British star sensibly wrapped up in a padded overcoat and woolly beanie hat.

In the movie, which is being touted as a darker reworking of the classic Victorian sleuth’s tale, Jude plays the stalwart assistant to Robert Downey Jr’s turn-of-the-century detective.

Also sharing the screen with the pair is RocknRolla actor Mark Strong, the detective’s rival, and Wedding Crashers’ actress Rachel McAdams.

Like any hands-on dad, the crown prince had prepared for any eventuality during their hiking expedition, carrying a backpack and a waterproof mat for making stops if needed.

He kept his hands free to guide their little boy along the snowy plain near the two hytte or cabins the royals bought last year in Uvdal, a picturesque ski resort three hours drive from their Oslo home.

The area, at the foot of Hardangervidda mountain range, is known for its blue skies, copious snowfall and a network of trails that criss-crosses the entire valley.

Asked on a US TV show what words of wisdom she’ll have on being introduced to Mrs Obama, Carla replied: “I must say she doesn’t need advice. It would be better for me to get advice from her!”.

Nicholas Sarkozy’s wife went on to pay tribute to the new president’s wife for the way she supported Mr Obama during his campaign. “She’s a great, strong, intelligent woman,” said model-turned-singer Carla.

As her French counterpart was looking forward to a new era in the executive mansion, Michelle, who describes herself as ‘Mom-In-Chief’ accompanied her daughters Sasha and Malia as they got the first glimpse of their new home.

During their tour the girls saw the bedrooms used by President Bush’s twins, Jenna and Barbara.

Mrs Obama wants to avoid significant changes to her daughters’ lives and has said they will still do chores like making their beds. “But I couldn’t help envisioning the girls running into their rooms and running down the hall with a dog,” she admitted during a TV interview.

The French actress’ vibrant organza, which featured blue bead appliqué at the neckline and sheer sleeves falling loosely around her slender arms, was a bold choice. And one the beautiful brunette pulled off with considerable aplomb as she attended the Christian Dior And Chinese Artists exhibition.

Also making the trip out East to help launch the show, which comprised of over 20 specially commissioned works by leading Chinese artists displayed alongside the Christian Dior creations which inspired them, was Marion Cotillard and J’Adore face Charlize Theron.

The South-African actress – who is being formally inducted as a UN messenger of peace in New York on Monday – was beautiful in a floor-length strapless gold gown as she arrived on the arm of Dior’s current head designer, John Galliano.

British designer Galliano made quite an entrance - partly due to having Hollywood star Charlize Theron on his arm and also with his choice of party-wear. The Gibraltar-born style maven, who later addressed guests at the event, chose an eye-catching suit adorned with hundreds of buttons.

Also turning heads in a pair of vertiginous red heels was British model du jour and Big Apple resident Agyness Deyn. Other key fashion players on hand to see new designer Alexander Wang presented with the Fashion Fund award included US Vogue editor Anna Wintour.

The $200,000 cash prize is given to the most promising up-and-coming designer of the past 12 months. This year Alexander impressed judges with his denim-orientated spring/summer 2009 collection, which received rave reviews when it was presented at New York Fashion Week.

The pair, who only announced their split last month, have reportedly reached an agreement by which custody of their two sons is shared 50/50 between them. Rocco, eight, and their three-year-old adopted son David, will divide their time between Madonna’s New York home and the film director’s base in London.

Although court documents reveal the singer cited ‘unreasonable behaviour’ on her husband’s part in the divorce petition, the couple have apparently impressed lawyers by reaching a remarkably smooth settlement over their assets.

Last night Guy was spotted taking his sons out to dinner in Liverpool where he’s currently lensing his latest film Sherlock Holmes, while, Madonna was back on stage in Philadelphia with her Sweet & Sticky world tour.

Looking particularly seasonal at the special screening of Four Christmases was new mum Minnie Driver who reflected the festive mood with a pretty white lacy mini teamed with a slick of red lippie.

And while the film’s male lead Vince Vaughn was absent other cast members - including Robert Duvall, who plays Vince’s father - were at the romcom’s preview.

Four Christmases, which is released in the US and UK on November 26, tells the story of San Francisco couple Brad and Kate – played by Vince and Reese – who find their usual holiday routine of escaping their families on an exotic break disrupted and are then forced to visit all four of their divorced parents on Christmas day.

In the past, stars like Penelope Cruz, Naomi Watts and Sophia Loren have posed for the Italian firm in glamorous locations such as Majorca and Saint Tropez.

In 2009, though, the images will feature largely unknown beauties roaming amidst animals in the wild. Typical of an approach intended to show how unspoilt the African landscape can be is the shot of a model leaping out of the lagoon, surrounded by water lilies and an elephant behind her.

Shot by Peter Beard, a photographer who’s lived in Kenya for 30 years and is renowned for his interpretations of the continent, the images celebrate “nature as a metaphysical entity”.

The Touch My Body singer outdid her own outrageous sartorial standards when she wore a fireman’s jacket - and little else - for an October 31 party in New York. The emergency garment was open in the front to reveal bejewelled red underwear, suspenders and stockings.

Her other half Nick Cannon had also donned a firefighter disguise - though he also had the T-shirt and trousers to match.

Adding impact to their smoking-hot entrance at the do - which doubled as a celebration for their six-month wedding anniversary - the duo pulled up in the back of fire truck.

“That’s the thing this time – we’re going to avoid everyone else’s pressure and go at our own pace,” said the actress while hosting a Halloween party at Rok Vegas Friday night.

Dressed as a Vegas cigarette and cigar girl, the Disaster Movie star was joined by fiancé Rob Patterson who wore a priest outfit with devil horns.

Spending time in the self-proclaimed Wedding Capital of The World didn’t give the couple any ideas. There are “no plans and no pressure” when it comes to a wedding, said Electra who was previously married to rocker Dave Navarro and NBA star Dennis Rodman

“Right now, we’re just taking things really slow,” she added

Electra, 36, and Patterson, 37, got engaged in April.
