Star magazine is reporting that Justin Timberlake and Cameron Diaz have gone their separate ways.

Now, normally I wouldn't place much stock in what Star says, but they were totally on top of that Jessica Simpleton/John Mayer thing, so we may have to start taking the tabloid a bit more seriously. On the other hand, this isn't the first time breakup rumors have surrounded Cameron and Justin, who have been together for three years.

The timing is about right for this thing to end anyway - Cameron is the ultimate serial monogamist, dating Matt Dillon for 3 years, and then suffering through a relationship with that wanker Jared Leto for another 4 years. It'll be awkward with the two of them having to do press for May's Shrek the Third, but I'm sure they'll get through it.

The person I'm most worried about here is me. If this rumor turns out to be true, it's going to be pretty difficult choosing sides on this one. I mean, god knows I love JT and can't wait to see him January 17 at the SaveMart Center. But I also adore Cameron, and was one of the people who actually spent the time and money to see The Holiday.

If only there was something - anything - that could cheer me up at this exact moment.
