Perfect gent: Channing Tatum attends to wife and glam co-star at Dear John event

On-screen lovers Channing and Amanda made a special appearance in London on Tuesday as they attended the unveiling of romantic drama, Dear John

Channing Tatum must have felt like a very lucky man this week.

Not only was he joined by his gorgeous co-star Amanda Seyfried at the UK premiere of Dear John, but he was also supported by his actress wife Jenna Dewan.

The trio made an appearance in the British capital to celebrate the unveiling of the romantic drama, which tells the story of a couple who are separated by armed conflicts and are only able to communicate through letters.

In the absence of Amanda's real life love interest – and Mamma Mia! co-star – Dominic Cooper, 29-year-old Channing proved to be the perfect gentleman, escorting the blonde star down the red carpet and cosying up for pictures.

And he was equally attentive to his wife of eight months.

The GI Joe actor proudly posed with Jenna – the couple wed in Malibu last July after meeting on the set on 2006 teen film Step Up – who could not take her eyes off her handsome husband.

If its success in America is anything to go by, Dear John will be a big hit in the UK when it is released on April 14 - the film knocked 3D blockbuster Avatar off the top spot at the box office.

Adapted from the novel by The Notebook author Nicholas Sparks, the movie tells the story of John and Savannah who meet during a summer holiday and fall in love. But their romance is threatened when John must return to life in the army.
