Reports questioning Britney Spears’ “changing” faith have emerged once again, after the singer was spotted sporting a Jewish symbol while sightseeing Paris.

The pop princess was taking time out from her hectic Circus tour, when she visited the Eiffel Tower with her sons, Sean Preston and Jayden James.

The singer, who grew up as a Baptist, was spotted wearing a Star of David necklace as she toured the French capital on July 7, reports the New York Daily News.

Britney has previously “experimented” with other religions.

She was introduced to Jewish mysticism Kabbalah by Madonna in 2003, following which the ‘Womanizer’ hitmaker began wearing the religion’s well-known red string bracelet.

But after giving birth to Sean, she announced: “My baby is my religion.”

Britney dabbled in Hinduism, and even visited a temple in 2006.

She was seen wearing Christian jewellery again, most recently during a trip back home to Louisiana in February.
