Source: Bang Showbiz NewsMila Kunis hasn't converted to Kabbalah despite attending a service with her boyfriend Ashton Kutcher in September.The 29-year-old 'Ted' actress was spotted accompanying her boyfriend of eight months Ashton Kutcher to Rosh Hashanah holiday services at the Kabbalah Centre in New York City in September but according to sources close to her 34-year-old boyfriend she hasn't started practising the religion's customs yet.An insider exclusively told BANG Showbiz: "Ashton is very serious about practicing Kosher. His team call ahead wherever he goes to make sure he won't have a problem because there are also a number of foods he won't eat. So far Mila hasn't followed suit and has never made any dietary requests like Ashton."Mila was reportedly raised Jewish and Kabbalah is said to have originally developed from its teachings.Sources previously revealed that the couple were seen arriving at the Kabbalah Centre holding hands on September 18 sparking rumours that Mila was converting to its school of thought.The insider said: "The men and women were separated (during the service), but Ashton always smiled at her. They were clapping and praying. She was taking it all in."Following the service, the 'Two and a Half Men' actor reportedly "ran to embrace her."The actor - who is currently visiting Mila in Rome, Italy, began following the sect in 2003 with his now-estranged wife Demi Moore. The couple turned to a Kabbalah counselling centre in a bid to save their marriage after he cheated on her last year.
