After a lifetime of looking at tabloids in grocery store checkouts, NO I don't believe any of them once in a great while they may stumble on the truth.
When it comes down to it I'm very interested in Rob and Kristen's careers, but what they do in their private lives is their business and not public domain, we as fans do not have a right to know.
If THEY choose to share their private lives with us then I'm interested of course who wouldn't be. However these rags print these stories only have one thing in mind and that's $$$$$$$$ not journalism or the truth, they are sensationalists who like stirring the pot to sell more magazines.
Save your money!!!!
And personally if Rob and Kristen are together I think they make a great couple and seem to have a lot in common. Is Rob a womanizer jumping from leading lady to another, sorry I just don't see it!
