Singer-songwriter Bruno Mars` long-term relationship is reportedly "on the rocks." The 38-year-old singer has been dating model Jessica Caban for 13 years, having started their relationship back in 2011. The 41-year-old is said to have spent Christmas and New Years away from Bruno, amid the reports about their shaky relationship, reports Mirror.co.uk.

Sources told The Sun, "Bruno Mars and Jessica barely spend time together anymore — it is really sad. They are living separate lives so it doesn`t bode well for their relationship. It feels like things are fizzling out between them.”
