Harry Styles, 19, lead singer of the popular One Direction boy band, is taking his interest in Judaism to the next level, by vowing to learn the Hebrew language in 2014, the UK’s Daily Star reported, citing an unnamed Styles pal.

“Harry’s made it his mission to learn to speak and write Hebrew,” the inside source said. “His obsession started with his tattoos, but now he’s becoming very serious about learning as much as he can. So far he’s learnt to write his name and One Direction in Hebrew.”

“Harry also loves kosher food. He regularly visits kosher restaurants in New York. He’s even organised for One Direction to play in Israel this year,” the source said.

Ben Winston, a director, Jew and friend of the band, has been mentoring Styles, the source said. “Ben has been helping him with Jewish cultural tips and Harry has even taken the prayers at their house on the Sabbath. He bought Ben a velvet, embroidered kippah from Jerusalem.”
