Scarlett Johansson has reportedly embarked on a romance with Hard-Fi frontman Richard Archer after growing close to the British rocker while filming in the UK.

Despite publicly stepping out with Pearl Harbor actor Josh Hartnett in the past few months, LOST IN TRANSLATION star Johansson has been in close contact with the cult musician.

The pair met in December (05) when Archer sent Johansson a personal invite to a London gig - knowing she was in the British capital filming Woody Allen's new movie SCOOP.

Since her return to America, the couple have enjoyed lengthy phone calls and are already planning to meet up again when Hard-Fi play in Los Angeles.

The band's spokesperson confirms, "Let's just say that Richard and Scarlett are very close at the moment. He has always fancied her and asked one of his managers to invite her to a gig.

"He knew she was in London so he thought, why not? The band are now touring Los Angeles. I am sure Richard will meet Scarlett there if there's time."
