The annual 2016 Sowetan LIVE Mzansi’s Sexiest 2016 big reveal took place at the Bon Hotel Midrand .
Social networkers are buzzing with speculation over who could've posted the pics.
The pictures - which leave nothing to the imagination - are suspected to have been leaked by a jealous ex or anyone who has a score to settle with the socialite.
But others suspect it was Mbau who posted the pictures just to get more attention.
We gotta ask, though: does she really need more public attention?
Some comments are on Mbau's hot bod and others are disgusted at the act.
Whoever posted them did not succeed in destroying the Queen of Bling's confidence because she has been tweeting over the past couple of days.
These are some of her tweets:
"A Diva Never Dies!!!!! #QOB"
"Thru all the bad we still smile, we laugh for we hold no sorrow @thetruetee, smile - #QOB"
"This tragedy has helped me sift out the Silver from Da-sylva! Love u all that has shown me unwavering love #ubrewedme #QOB"
