Jennifer Frost (born February 22, 1978, Liverpool), is an English singer, model, and member of Atomic Kitten.
Jenny started her musical career in 1998 in the girl-band Precious, which became famous by winning the right to represent the UK at the Eurovision Song Contest in 1999, with the song "Say It Again". In a strange reversal of what has frequently happened to British entries, this success propelled Jenny and the band to a big hit in the UK charts, while they flopped at the contest itself, finishing only twelfth. Subsequent releases by Precious enjoyed only modest success and Jenny moved on by replacing Kerry Katona in Atomic Kitten in 2001, just in time to bask in the reflected glory of the band's first UK No 1 single, "Whole Again".

Jenny got engaged with DJ Dom Thrupp in 2002, however the couple has no intention of getting married yet. After the split of Atomic Kitten, Jenny has embarked on a solo career and released her first single Crash Landing on October 10, 2005, which failed to reach the Top 40. Jenny originally recorded the song for the band Route 1, but decided to remake it and shoot a video for the song which features Jenny in a spaceship in a pink/purple setting.

She has recently appeared on the 2005 edition of I'm a Celebrity, Get Me Out of Here! on the ITV network. Jenny is also part of Premier Model Management and does various modelling assignments like being the face of an underwear range.

Jenny's new song "Bad Girl" is available from her official myspace. The song was originally written for Jennifer Lopez' Enough movie and was written by Frost's boyfriend Dom Thrupp.
