Mutya Buena

Buena departed Sugababes in December 2005, after which she embarked on a solo career. Her debut solo album, Real Girl, was released in June 2007 through Island Records. The album spawned three top-twenty entries on the UK singles chart; the title track which reached number two, "Song 4 Mutya (Out of Control)" (with Groove Armada) which reached number eight, and "This Is Not Real Love" (with George Michael) reaching number fifteen. Real Girl entered the top ten on the UK Albums Chart and was certified gold by the British Phonographic Industry (BPI). Following the underperformance of the album's final two singles, "Just a Little Bit" and "B Boy Baby", Buena parted ways with Island Records in 2008. She subsequently collaborated with various independent artists, including Ashley Walters, Don-E, Gak Jonze, and Coree Richards of Damage.
In 2012, Buena reunited with her former Sugababes bandmates Siobhán Donaghy and Keisha Buchanan. The original trio opted to release music under the name MKS (Mutya Keisha Siobhan). Their first single, "Flatline", was released in 2013 under Polydor Records, to moderate commercial success, after which the group entered a period of inactivity from the following year. In 2019, the group regained the rights to use the Sugababes name, and subsequently returned to releasing music and live performing. That year, The Guardian ranked Buena second on their list of the best girl band members of all time.
As a member of Sugababes, Buena has received several awards, including a Brit Award, a MOBO Award, and a BMI Award, while her solo career has earned her nominations for the former two. In addition to her music career, Buena has also appeared in multiple television shows, including Celebrity Big Brother (2009), Celebrity Coach Trip (2019), and Celebrity MasterChef (2024). In 2025, Buena released her autobiography, Real Girl, which details her life and career.
