Thulo is an actress who has appeared on e.tv's 4Play Sex Tips For Girls and is currently presenting Zoned: Wanna Be Famous on SABC1.
The two were crowned Mzansi's sexiest celebrities in Rosebank, Johannesburg, last night.
They were voted for by Sowetan readers on the newspaper's SowetanLive online.
After a year contracted to M-Net soapie The Wild, Yeni joined SA's leading soapie, Generations, on SABC1 where he plays Phenyo Mazibuko, a Durban-born corporate lawyer who has relocated to Johannesburg.
Thulo said her confidence makes her sexy, and added: "Confidence is who you are and being comfortable in your own skin is the sexiest look, always".
On how she maintains her sexy look, the North West-born Thulo said: "I always remain true to my values and stand firm in what I believe in. That way I'm not easily swayed".
Female celebrities who are in the top six with Thulo are Big Brother Stargame housemate 2012 Babalwa Mneno, host of LKG show Lerato Kganyago, Generations actress Zenande Mfenyane, FHM model Ellen Mahlangu and actress Gail Nkoane.
