Modeling and magazine appearances:
Ellison is currently featured in Maxim magazine's Girls of Maxim gallery. She has appeared regularly in almost all of the mainstream British "lads' magazines" over the last eight years, though her first appearance was in 1999 in a sexually suggestive shoot for FHM at the age of just 16, under the heading "Jailbait". Recently, Ellison took over a contract with lingerie giant Ultimo for its "Young Attitude" line from fellow model Jordan barely two months after she had been signed on. Though Ultimo boss Michelle More had chosen Jordan for being "sexy, fun and outgoing," she later changed her mind, stating, "Jordan was just the wrong choice for [us]. Jennifer is a far better option and far classier." In 2005 Ellison was voted "world's sexiest blonde" by readers of the UK magazine Nuts, beating model Victoria Silvstedt, who came second, and pop superstar Britney Spears, who was voted third. Ellison is also a regular in the yearly FHM "100 Sexiest Women in the World" feature. She first appeared in 2003 at number 60; then at number 29 in 2004; by 2005 she was at number 17; in 2006 she was number 31; in 2007, she fell to number 87; and in 2008 she did not feature. Her drop down the list over the last two years is largely attributable to her taking a break from modeling from late 2006 to early 2008. However, she has since returned to modeling. She won the Rear of the Year award in 2008.
Ellison studied dance from the age of three, first at a dance school in Liverpool, then later at the Elizabeth Hill School of Dancing in St. Helens, Merseyside. She has achieved examination passes with the Royal Academy of Dance and appears on the RAD's instructional video for the Intermediate Foundation syllabus. She has also taken examinations with International Dance Teachers Association and also won Ballet and Modern Dance titles at the IDTA Theatre Dance Championships in in 1996 and 1997. Choosing to pursue a professional career in dance, she successfully auditioned for the Royal Ballet Lower School, but was asked to leave after two years due to a large bust, which ruined her lines for classical ballet.
In 2006, Ellison released Jennifer Ellison's West End Workout, a fitness DVD which combined her love of dance with exercise routines.
