How lucky is Justin Timberlake? Not only has the man had a successful career in a boy band, and even more successful career as a solo artist and a fledgling acting career, Timberlake has been attracting all sorts of women since becoming single. And, let's not forget that he had to dump Cameron Diaz in order to become single once more. As a bachelor, Justin Timberlake has been the focus of rumors that romantically link him to Scarlett Johansson and Jessica Biel, and after the Super Bowl weekend, at least one of those two rumors seems to be confirmed.

Even though Timberlake was seen with Jessica Biel at the Sundance Film Festival a week and a half ago, Justin chose to take Scarlett Johansson as his guest to the Super Bowl in Miami, Florida. An insider was quoted by In Touch magazine as saying that Justin and Scarlett "spent the whole weekend together. They were dancing and whispering in each other's ears. They were having a really good time together." Rumors of a romantic link between Scarlett Johansson, 22, and Justin Timberlake, 26, began to circulate after Timberlake split with Cameron Diaz, whom he had dated for the past three years. After the break-up, Justin recruited Scarlett Johansson to be in his next music video, "What Goes Around...Comes Around", which debuts later this week.

While Scarlett and Justin had been spotted together before the music video shoot, most notably at the after-party for the premiere of Timberlake's Alpha Dog, an Us Weekly quoted a Timberlake insider who said that Justin's ex-girlfriend was incredibly upset by the music video shoot. ""(Cameron) could not believe he went behind her back to put her in the video. Cameron was very jealous of Scarlett." But if Cameron Diaz was jealous of Scarlett for the music video shoot, Diaz must be livid after the events of this weekend. The New York Post and their Page Six spies caught a sight of Justin and Scarlett that could make anybody fly into a jealous rage, as the two were seen chatting and dancing, holding hands, "Then, as they left through the back, Justin was leaning against the wall and Scarlett came up, leaned into him and did a sexy, little dance, grinding into his body."

Star magazine also had reporters on the scene, who said that, ""[Scarlett] looked super-cute in a simple ponytail, black headband, dark jeans and a tank-top. She was bubbly and relaxed as she chatted with friends who joined them at the table. Justin, who sat next to Scarlett, was wearing jeans and a windbreaker jacket that he kept zipped up to his neck all night." And, as if one eyewitness account of their dance moment wasn't enough, Star magazine talked to another source, who said, "[Scarlett] had [Justin] up against the wall and was grinding against him while they were waiting for their car!"

In Touch insiders reportedly spotted Justin and Johansson enjoying a nightcap at Timberlake's bungalow in the Delano Hotel, where he was staying during his Miami trip. While celebrity magazines have been having a field day with the rumors, Justin Timberlake's rep was quoted by E Online as saying he had "no idea" if the reports were true, while Johansson's rep said they wouldn't "comment on client's personal lives but thanks for asking." With no confirmation of a relationship coming, the love interests of these young celebs seems to have a life of its own. See if you can follow: Justin Timberlake broke up with Cameron Diaz and may or may not be involved with Jessica Biel, Scarlett Johansson, or, according to Life & Style, Alyssa Milano. All the while, Timberlake's former girlfriend, the newly-single Britney Spears, is rumor to want her old man back.

As all this is going on, Cameron Diaz has been spotted surfing with potential new boyfriend Kelly Slater, and Scarlett Johansson's ex-beau Josh Hartnett, recently talked about the end of their relationship, though he has been linked to Jude Law's ex, Sienna Miller, as well as Spider-Man star Kirsten Dunst. Officially, none of these people are a couple, though.
