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, and will also be joined by another live act yet to be revealed.

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.
