In pictures: Bradley Cooper and Suki Waterhouse's cutest moments

Hands intertwined, chatting intimately together, Bradley Cooper and Suki Waterhouse look like they're in a world of their own even at the most high profile galas.

Since meeting this time last year, the couple have been inseparable, with him whisking the 22-year-old around the world on his promotional tour for American Hustle.

The globetrotting love affair began in London when Suki, a model who is good friends with the Delevingne sisters Poppy and Cara, was introduced to the Oscar-nominated actor. Bradley, 39, immediately won her over with his "ridiculously good dancing," she recently revealed.

In one of her first interviews on the romance, the London girl said he invited her to the Cirque Le Soir nightclub and impressed her with the way he was tearing up the dancefloor.

Previously she's declined to talk about him, saying: "The truth is if I start talking about him, I probably won't be able to stop."

It's clear they are completely smitten and Bradley is attracted to his girlfriend's zest for life. Suki is a self-confessed tomboy, who loves surfing, karate and rock climbing. She's also a keen photographer, who has a few parts in films.

As well as attending the BAFTAs together on Sunday, the duo have been guests of Michelle and Barack Obama at the White House. Bradley and Suki were seen deep in conversation with US Secretary of State John Kerry.

It's thought the Hollywood star was invited because he spent six months in France studying the language so would have had no problem chatting with President François Hollande, who was the guest of honour.

At Halloween the duo had fun at a party thrown by Kate Hudson. Other A-listers the British beauty has met through her boyfriend include Ben Affleck and Gerald Butler.

Suki has also been seen several times in Hawaii, where her beau is filming a project with Emily Blunt's husband John Krasinski.
