Shakeup or Breakup?

Uh-Oh .... Justin 'Sexy back' Timberlake and wifey Jessica Biel. Is another Hollywood divorce on the horizon? There are rumors spreading that Justin Timberlake and Jessica Biel might be on the brink of splitting up. Some recent behavior from the two has everyone wondering if these two are going to stick it out. 

Jessica wasn’t present at Justin’s appearance on Saturday Night Live and JT was spotted without his wedding band on during his new tour.
“Justin was solo again at the Saturday Night Live after party and he stayed until nearly 5 a.m.,” a fellow partygoer exclusively told Radar.
“Everyone was buzzing about her absence.”
“She wasn’t with him at rehearsals on Friday either, which was sort of weird,” the source said.
“And it’s not that Justin was flirting with other women or anything at the party but something just didn’t seem right. It was literally what everyone was talking about; whether he and Jessica have split.”

Timberlake did have his wedding band on at the party but barely spoke of his wife, the insider revealed. She does have a career of her own as an actress, so their schedules could just be conflicting. Plus they seem to be a private couple, but you never know.
What do you think…are they on the verge of a break up or is just media sensationalism?
