Justin Timberlake Will Marry Jessica Biel

After going on a break earlier this year and then rekindling their romance in the summer, Jessica Biel and Justin Timberlake might actually take their relationship a step farther, says a new report – but there's a big “if” to it.

The latest print issue of Us Weekly (story via here) claims the only reason Justin has been holding out on marrying Jessica is because he believes it would ruin his career, even though she's been very clear about where she stands on the issue.

However, should she threaten him to leave him again, he'd marry her, the tab writes.

“When Justin Timberlake, 30, and Jessica Biel, 29, reconciled in July after a five-month split, friends assumed this time they’d marry,” the celebrity publication writes.

Whether they end up walking down the aisle is entirely dependent on Jessica, an unnamed source close with the situation, explains.

“Justin thinks marriage would hurt his career, but if Jessica threatened to leave, he’d do it. He doesn't want to lose her,” the insider dishes.

Contacted for comment, Justin's publicist only said that he “separates his personal and professional lives.”

Fans must know that Justin and Jessica were believed to be on the verge of marrying at least a handful of times, but they never really went through with it.

Their split of earlier this year was a very amicable one, with either star refusing to get into details. Speculation in the media, though, said that it was her nagging to commit and settle down (i.e. marry) that drove the final nail in the coffin of their romance.

Surprisingly enough, just a short while after the breakup statement came out, the two were back together again, which has prompted some speculation that they might have just been “on a break.”

Jessica and Justin have always notoriously kept their personal lives to themselves, so don't expect to hear anything about the so-called marriage plans from them – at least, not until the deed is done and they are married.
