Mila Kunis

Ashton Kutcher and Mila Kunis held hands and covered up in hooded sweatshirts during a rainy outing in Hampstead, North London, today. The couple grabbed lunch at an Italian restaurant before stopping for dessert at a crepe stand and devouring their sweets during the walk home.

Ashton has joined Mila across the pond while she films Jupiter Ascending with Channing Tatum, who also has the company of his pregnant wife, Jenna Dewan, in the UK. Mila and Ashton have welcomed the London scene and cuisine rather quickly and had a double date with Princess Beatrice and her boyfriend, Dave Clark, on Saturday. The foursome reportedly indulged in deep-fried bananas and tequila shots at two different locations, including London hot spot Duck & Waffle.

Mila Kunis and her Jupiter Ascending costar Channing Tatum had a night out in London yesterday with their significant others. She brought along boyfriend Ashton Kutcher, while Channing had the company of his pregnant wife, Jenna Dewan. The foursome were reportedly able to attend the premiere of the English National Opera's Sunken Garden at the Barbican Center. The evening of opera was a bit of a change from the sci-fi material Mila and Channing have been busy with. Work on Jupiter Ascending has both Channing and Mila hunkering down in the English capital for a good period of time. Mila's apparently staying in the city itself, while Channing and Jenna are enjoying the last weeks of her pregnancy at Sienna Miller's house outside of London in the Cotswolds.

Ashton Kutcher joined Mila Kunis in London last night. The couple shared a dinner date at Scott's restaurant after attending Mila's Gemfields jewelry event together. Mila is the brand ambassador for Gemfields and she celebrated her recent appointment at a party for the brand in LA last month.

Mila's moving on to her jewelry duties following a press tour for her latest film, Oz the Great and Powerful, which took her overseas as well. She debuted the film in Moscow with costars James Franco and Michelle Williams before hitting the yellow brick road in an Alexander McQueen gown for the UK premiere at the end of February.

With Oz the Great and Powerful currently in theaters, we're reacquainted with some classic movie characters that first graced the screen in The Wizard of Oz 74 years ago. Since this is a prequel of sorts and focuses on the wizard (played by James Franco), we don't see all of the characters you know and love (sorry, Dorothy), but there are a few younger, slightly different versions of a few familiar Oz denizens. Click through to see how the shiny new class stacks up against the originals.

Oz the Great and Powerful is out today in theaters, but the red-carpet (or should we say, yellow brick road) glamour leading up to the film's premiere actually started weeks ago. To promote the film, Michelle Williams, Mila Kunis, and Rachel Weisz traveled around the world — Moscow, Tokyo, London, and Los Angeles, to be exact — bringing their individual brand of glamour to each city for the movie's debut. From understated Michael Kors and statement-making Lanvin to peacock-feathered Burberry and one sexy formfitting Atelier Versace number, these starlets certainly turned up the evening elegance tenfold for Oz.
