BRITNEY SPEARS - WRITER CLAIMS BRITNEY'S 'PHYSICAL' BECAUSE OF BIRTH NUMBER ONE

The author of a quirky new book, which aims to link modern pop stars to the hits that were number one in America when they were born, has unearthed BRITNEY SPEARS was born to the tune of OLIVIA NEWTON JOHN's PHYSICAL.

In POPSTROLOGY, IAN VAN TUYL claims future pop and rock stars live out the lyrics of songs that were top chart hits when they were born.

Van Tuyl claims Newton-John's sweaty gym anthem has become the soundtrack to Spears' life.

He also reveals COURTNEY LOVE was born when the BEACH BOYS' I GET AROUND was at the top of the charts and naughty EMINEM was born to the tune MY DING-A-LING by another controversial music man CHUCK BERRY.
