Scarlett Johansson has partied with Justin Timberlake
, but she is mum on relationship rumors about the pair.
"We live in a world today where if two people are single – and one's a guy and one's a girl and they're both famous – you're going to be linked with somebody," the actress, 22, tells Seventeen
for its May issue, when asked about the two of them. "If it's somebody one week, it's going to be somebody else the next week. It's either me or Jessica Biel."
Johansson, who most recently dated her Black Dahlia
co-star Josh Hartnett, says she's not focused on finding a boyfriend. "When I'm single, I don't focus," she says. "I focus on a guy if he's a boyfriend, but I don't focus on finding
a boyfriend." With a laugh, she adds, "They're never around when you want them."
In February, while being roasted by Harvard's Hasty Pudding Club
, she announced that her dream date was "Probably Patrick Swayze."
Her first love, she also reveals to Seventeen
, was "a great boyfriend in high school. ... I totally thought we were going to be together forever, which is how it should be."
When she is with a boyfriend, she says, "If someone is straightforward with me, I'm very confident. But if he's playing a weird mind game, I get very self-conscious."
Still, were she to be in a relationship, she says she would like it to be surrounded by a sense of mystery.
"I can't stand mind games," she says. "But I think you should be mysterious and flirtatious. You should always have some mystery in a relationship. You don't wanna know what the person's thinking all the time. And you don't want him to know what you're thinking all the time."
