There is nothing sexier than a man wearing a matching top to yours, especially if it is a spandex work out top.  We spotted Dax Shepard and Kristen Bell sharing a kiss yesterday on the set of When in Rome.  Not sure if it was an out take or part of the scene, but the lovers in green seemed to be enjoying each other's company...maybe afterwards they took turns braiding each other's hair!

      

We spotted real life couple Kristen Bell and Dax Shepard on the set of their new movie When in Rome in NYC yesterday afternoon.  The movie is about a young art curator (Kristen) who picks up a coin from the fountain of love and finds herself with an overabundance of suitors, including one played by Dax. 

      

We caught Dax Shepard on the streets of NYC yesterday, looking very committed to his oral hygiene.

There's nothing like some sun during the holidays to get the hormones going. And they certainly were rampant when we came across lovers Kristen Bell and Dax Shepard making out on the sand in Miami. Kristen and Dax only had eyes for each other as they kissed and hugged for photographers. Do we sense another celebrity wedding in the making? Watch this space...

Okay, so we know it's probably not the name that will finally stick, but Kadax are definitely Hollywood's new hot couple. As our exclusive pictures show, Kate Hudson and Dax Shepard couldn't keep their hands off each other at during a weekend break at Goldie Hawn and Kurt Russell's Canadian holiday home. And just as our pictures were going public, Kate's estranged hubby Chris Robinson put his new girlfriend on display. Do we detect a bit of media tit-for-tat going on here?
