Charlize Theron glammed up the red carpet last night as she attended the premiere of her latest movie alongside Will Smith.

The actress plays Smith’s wife in Hancock and the co-stars certainly seemed to have enjoyed the experience as they laughed and joked with each other in front of the cameras.

Playful Smith even nuzzled and bit the 32-year-old's neck as they posed for photographers.

The South African beauty - who showed off her legs in a sultry black dress with a slit up the side at the event - has previously spoken of her affection for the father-of-three, admitting that she loves working with him and even gets star struck when she's in his presence.

'I would make a film about a tape recorder with Will Smith! I love working with him, he's an incredible actor,' she said.

Thousands of fans screamed for Smith - who is married to actress Jada Pinkett Smith - as he went on a walkabout.

Smith, who took to one of the stages to address fans directly, said: 'You guys always take really good care of me... this is a beautiful thing.'

He said of his character: 'Hancock is a bit of a drinker and he's kind of an alcoholic superhero... we worked really hard and concentrated on this film to try and create something that was different.'

Asked about his golf handicap, Smith said: 'I'm probably a 14 right now.'

Theron added: 'I'm a seven. Also I'm an actor which means I lie.'
