Rihanna and Chris Martin are reportedly worried about Jay Z's marriage to Beyonce. The singers met up for dinner last week to talk about Jay Z, who has distanced himself from his friends following rumours that his marriage to Beyonce is on the rocks, reported Contactmusic. "Rihanna and Chris met up because they are worried about Jay. Apparently he hasn't been in touch lately, ever since his marriage problems surfaced," a source said. The Coldplay frontman is particularly keen to offer support to his friends following the demise of his own marriage to Gwyneth Paltrow earlier this year.
