They're the most pretentious couple in all of Christendom, but Chris Martin and Gwyneth Paltrow still made a rare public appearance together at the Golden Globes this weekend. Still, the couple can't seem to shake the rumors that they're headed for splitsville. 

According to Us Weekly, even though the couple was seen together at the Golden Globes -- and even engaged in a bit of PDA -- the tension between them was palpable, and commented on by such people as Dlisted.com. According to the same site, though, it's because Gwyneth doesn't want their relationship to play out in the public eye. 

"It doesn't behoove us to be a public couple," Paltrow told ELLE UK in 2009 of her husband. "He certainly doesn't want that. We've never ever walked down a red carpet together, we never will."

It looks like they went back on their own words... but why, though?

Well, for starters, it seems like this stems back to an interview in September, when Gwyneth told an interviewer that she would forgive Chris Martin if he were ever caught cheating. "I think that if the idea of being committed to someone is important to you, you begin to value certain parts of your social life over another," Gwyneth said. "No couple is the same, and as such, every couple takes on different challenges. I would like to think that I would be forgiving and/or forgiven, but I can't give an honest answer as I haven't really experienced that." 

Then came the rumors from Vanity Fair late last year that Gwyneth has been having an ongoing affair with Miami billionaire Jeff Sofer, during a time when she & Martin were "on a break." 

According to Celebrity Dirty Laundry, "apparently, Gwyneth fears that with all of that digging, the magazine may have uncovered the truth about her affair with Jeff that dates back to 2008 when she and her rocker hubby, Chris Martin were rumored to be on the rocks. That guy is in the running for sainthood to choose to live with a snippy witch like Gwyneth and he puts up with a lot, but infidelity would be a game changer. If Chris gets confirmation that his wife has had an affair it will provide him with a good excuse to hit the bricks and don't think for a second he won't do it!" 

So... are the couple on the rocks? Time will tell!
