[5] She later worked on a range of advertising campaigns, including Foster's Lager, Renault Mégane, Walker's crisps, Piz Buin and Bravissimo, a company that specialises in bras and lingerie for large-breasted women.

Soon after, she caught the eye of the editorial team of the Daily Star tabloid,[9] which began featuring her as a Page Three girl.

[10] In February 2007, it was announced that Brook had signed a contract, reported to be worth around £1m, to represent Unilever's Lynx body spray, known as "Axe" in the US and in continental Europe.

[15] In October 2010, Brook appeared live at Clapham Picture House to surprise cinemagoers as part of a promotion for Carlsberg and Sky 3D.

She played the girlfriend of Clark Kent/Superman's nemesis Lex Luthor in four episodes of the American science fiction drama Smallville during the show's first season (2001–02).

[20] In 2004, she played character Nikki Morris in the video game Need for Speed Underground 2, alongside Brooke Burke.

[9] Brook had a breakthrough into mainstream presenting in January 1999, when she was chosen to replace Denise van Outen as the female half of The Big Breakfast hosting team, alongside Johnny Vaughan.

Brook and Fortuna were put into fourth place, but with the studio audience's vote, they came second to Jill Halfpenny and Darren Bennett.

In 2008, Brook took Jennifer Ellison's place as one of the three judges on the second series of the reality TV programme Dirty Dancing: The Time of Your Life,[37] broadcast between September and November 2008.

In January 2009, she joined the third series of Britain's Got Talent as a fourth judge but was subsequently axed from the programme after less than a week on the panel, the producers having decided the four-judge format was "too complicated".

[40] Domestic violence groups criticised her during her promotional tour for laughing about punching ex-boyfriends Jason Statham and Danny Cipriani in the face.

[3] In 2014, on an appearance on ITV's This Morning, she admitted to punching previous boyfriends Jason Statham and Danny Cipriani in the face, with Men's Domestic Abuse charity Menkind subsequently issuing a statement saying it was "extremely disappointed" by the segment.
