Jenny McCarthy compares her childhood devotion to Jesus to teens’ religious adoration of Justin Bieber.

The 39-year-old former Playboy Playmate went to church at least twice a week as a child and even wanted to be a nun, she disclosed in new book Bad Habits: Confessions of a Recovering Catholic.

Jenny revealed that unlike most kids her age who are obsessed with rock stars, her teen idol was the son of God.

“I had a Jesus poster, the Pope was over there, I had some ‘I love Jesus’ t-shirts and bags hanging up. Jesus was my Justin Bieber,” she said to a camera crew that she brought to the Chicago, Illinois home where she grew up during a recent interview on US programme Nightline.

Meanwhile, Baby crooner Justin will join pop music’s bad girl Rihanna for a star-studded performance at the annual Victoria’s Secret Fashion Show, it was announced today.

Rihanna is expected to perform two songs from her upcoming seventh album, including her newly-released single Diamonds.

The Victoria’s Secret extravaganza, which will feature the lingerie brand’s Angels Miranda Kerr, Alessandra Ambrosio and Adriana Lima, is scheduled to air on December 4 2012 on US television network CBS.
