Tom, who? Indeed, there seems to be trouble in paradise, as Vanderpump Rules star Kristen Doute has recently posted a photo of herself cozying up to a hot new guy at a Grammys party. Does this mean that Kristen and longtime boyfriend Tom Sandoval are officially dunzo?

Kritsen and Tom have certainly had their ups and downs lately as a couple. Indeed, Season 2 of VR has shown how much the two have been through, including Tom admitting to having hooked up with Ariana Madix, not to mention Stassi Schroeder accusing Kristen of sleeping with Jax Taylor. Twice.

Yet Tom and Kristen have appeared to remain strong throughout all the rumors, with Kristen posting a photo of the two of them cuddling on a date night in late October 2013.

However, on January 26, Kristen posted the photo at right of herself with a smokin' hot mystery man. "@billboard grammy party," Kristen captions the shot.

So just who is this dude? And are he and Kristen more than just friends? We're not sure, but he appears in several pics on Kristen's Instagram page from the past few weeks. Tellingly, there haven't been any pics of Kristen and Tom up there in a while.

We're bound to learn more about Kristen and Tom's status when the show's Season 2 reunion airs next week on Bravo. We shall see!

Do you think Kristen is dating this new guy? Or would you rather see her patch things up with Tom?
