[21][22] On 2 December 2018, Matheba co-hosted the Global Citizen: Mandela 100 concert alongside comedian Trevor Noah, supermodel Naomi Campbell and other notable public figures.

[23] In 2008, Matheba made her debut drama role on the SABC 1 show, InterSEXions where she played Nurse Seipati.

[31] In 2009, Matheba received a call from radio station YFM in which she was told that she'll be added to the new line-up of presenters.

[32] She received her own weekend afternoon show called, "The B* Hive", which was an instant success mainly focusing on young listeners.

[35] Matheba's slot show The Front Row, had a great and joyful listenership until a dispute with the radio station's manager, after an on-air reshuffle that saw Bonang hosting the show alongside her rumored longtime industry rival Lerato Kganyago without her notification arose.

The T-shirts had famous Bonang quotes printed on them, including "Mo'ghel", "Give The People What They Want" and "#IAmBonang".

[49][50] Other Bonang's endorsements include Peugeot, BIC Razors, Brutal Fruit, Diva Divine Hair, Lifestyle Pads, and Courvoisier.

Matheba refuted these claims, stating: "I never anticipated how badly I would be treated when the story of my break-up was leaked.
