Further singles from the album, "Mi Chico Latino" and "Lift Me Up", became UK number ones with the latter outselling Halliwell's former bandmate Emma Bunton. The fourth single, "Bag It Up", also reached number one.

In 2001 Halliwell followed up with her second album, Scream If You Wanna Go Faster. It also included her cover version of the Weather Girls' 1983 hit, "It's Raining Men", used on the Bridget Jones's Diary film soundtrack. The song became a huge hit, selling over 4 million copies worldwide, in the United World Chart it hit number two (behind "Lady Marmalade" by Christina Aguilera, Lil' Kim, Mya & Pink) based on Sales, Airplay and Votes, it became the second best selling single of 2001.

The books are scheduled to be released in May, 2008.

On June 28, 2007, Halliwell announced she was joining her former colleagues for "The Return of the Spice Girls", a global tour that would see all five original members of the Spice Girls together on stage for the first time since Halliwell walked out mid-tour in 1998. Part of the setlist of the reunion tour features Halliwell performing solo, singing her hit single 'It's Raining Men'.
