Beyonce Knowles is literally stopping traffic in Japan with a new giant billboard advertisement.

The Bootylicous star shows off her cleavage as she poses in the arms of a Japanese pop star for handbag brand Samantha Thavasa.

The Sasha Fierce star looks stunning as she towers over Tokyo in a figure-hugging dress with a plunging neckline.

The lucky chap in the billboard campaign is Takuya Kimura, a singer for Japanese group SMAP.

"Kimura is very handsome, strong, manly and sexy," said Beyonce.

The pop star returned the compliment, stating: "I enjoyed the time with her. She is really sexy and cute."
