Rebecca was born on July 26, 1977 in Sydney, Australia, to David and Helen Smallbone. Her musical career began in 1990 when she opened shows for CCM artist Carman during his Australian tour. In 1991, she released her first album, Refresh My Heart under the name Rebecca Jean. Later that year, she moved to the United States upon signing with ForeFront Records, and took her stage name at the label's request.

CRW Magazine has named Rebecca to the list of the “50 Most Influential People in Contemporary Music.” Her book, “Wait For Me,” now in a 9th printing reached the #1 spot on the prestigious CBA (Young Adult) book chart in 2003, with Rebecca’s passionate, and often controversial, challenge to young people to “stand strong” with her on issues of sexual purity. She closed out 2004 with the much anticipated release of her new book, “SHE,”on Tyndale. An impactful “where the rubber meets the road guidebook,” for women of her generation, in “SHE” Rebecca gives a controversial and impassioned voice for a modern womanhood based on a return to biblical principles. The “teen” edition of the book—SHE TEEN—launched in September of ’05—quickly reaching #1 on the CBA Young Adult Chart.

In April of 2006, she won a Dove Award--Christian music’s highest honor—for her participation in the “Special Event Album Of The Year”—for the Chronicles of Narnia: The Lion, The Witch & The Wardrobe, for which her dramatically charged song Lion was a centerpiece.

In January 2007, she was for the 6th consecutive year named “Favorite Female Artist” in Contemporary Christian Music by the more than 27,000 votes cast by readers of CCM Magazine, considered the flagship publication of the Christian genre. Rebecca also repeated with the “Best Female Artist of 2006” award—her fourth consecutive year to be given this honor, with sales of her music soaring around the globe, her signature blend of modern pop/rock sensibilities and lyrics of unwavering devotion, has blazed straight to the heart of an entire generation. Her path has led to 17 Top 10 singles--#9 of which reached the #1 spot on the charts.

Her latest album, If I Had One ChanceTo Tell You Something, was released in November from EMI. One of the most anticipated albums in recent Christian Music history, it contains Rebecca’s trademarked passion for unique self-written music—from rock and pop to symphony—her first full on studio album in five years If I Had One ChanceTo Tell You Something sonically embraces her passionate lyrics of devotion and praise to God.
