Justin Timberlake "In Love" With Jessica Biel

After months of playing the field since his split from Cameron Diaz, is Justin Timberlake ready to "go steady" with Jessica Biel?

Or is this just another illusion... the kind Criss Angel would perform? Sorry, that may have been the worst attempt at cleverness ever.

Timberlake and Jessica Biel, who were first linked at a Golden Globe after-party in January, recently spent several days together in the U.K., where Timberlake was touring.

They holed up in Manchester's five-star Lowry Hotel and took in a soccer match. No word on whether Biel complained about not getting A-list roles because she's too hot.

And now "Justin's in love," a source supposedly tight with the ex of Britney Spears and "FutureSex/LoveSounds" singer tells People in its new issue.

Knowing Justin Timberlake's feelings toward celebrity gossip, that friend is probably not going to be one for long.

"She's the coolest chick ever. He wants to be with her all the time. He's ready to be serious," says the pal of Justin Timberlake.

Over the last few months, Timberlake, 26, and Biel, 25, have also been spotted snowboarding with pals at the Sundance Film Festival, and Biel recently attended a barbeque at Timberlake's L.A. home.Biel, you may recall, was recently linked to Derek Jeter.

Prior to that, Justin was supposedly with Scarlett Johansson. Not shabby. Though we wonder if he could ever convince her to sit topless in the sink.
