During an interview with Vogue magazine, the 22 year-old starlet claims to have never dated the 26 year-old actor and singer.
Since splitting with his long-time girlfriend, Cameron Diaz, Timberlake has been considered one of the most eligible bachelors in the world.
Johansson added that she did not get in between Timberlake and actress Jessica Biel. According to rumours, Timberlake was dating both Johansson and Biel following his split from Diaz.
Scarlett Johansson starred in Timberlake’s music video for the song What Goes Around Comes Around, in which the two stars share a passionate kiss. Johansson said of the video, "We had fun together. I think this (rumor) happens because we’re both single and in the spotlight, and obviously Justin’s a very high-profile person."
