Mila Kunis is thinking about converting to Kabbalah.

The Ted actress was spotted accompanying her boyfriend Ashton Kutcher to Rosh Hashanah holiday services at the Kabbalah Center in New York City last month. "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," a source told Us Weekly.

The couple were seen arriving at the center holding hands on September 18. Following the service, the Two and a Half Men actor reportedly "ran to embrace her."

The 34-year-old actor began following the sect in 2003 with his now-estranged wife Demi Moore. The couple turned to a Kabbalah counselling center in a bid to save their marriage after he cheated on her last year. Ashton is said to be determined to make his new relationship with his 29-year-old former That 70s Show co-star last.
