In September 2009, Allen announced that she was considering a career in acting, that she would not renew her record contract, and that she had "no plans" to make another record. In September 2010, she gave her last performance for two and a half years, supporting Muse at Wembley Stadium in London, England. She featured on the UK top five single, "Just Be Good to Green" by Professor Green in June 2010. The following month, she started writing songs for the musical version of "Bridget Jones's Diary" which was scheduled to open in London's West End in 2012. Also in 2011, T-Pain used a verse from Allen's "Who'd Have Known" as the chorus to the song "5 O'Clock", which became the second single from his album "Revolver". The song, which also features Wiz Khalifa, was released in September 2011, and reached number ten on the ""Billboard" Hot 100" chart, making it Allen's first Top 10 single in the United States.
