Taking to her Instagram on Tuesday, Nombona who plays Monde on the award-winning female prison drama series, paid a heartfelt tribute to the show’s director and writer Mandla N.
But tweeps thought there is more than meets the eye, as speculations of the duo dating starting making rounds on social.
However, the director and writer was met with a lot of budding birthday tweets from his peers and co-stars but those tweets weren't as "juicy" to the people it seems.
Industry friends including radio personality and entrepreneur DJ Sbu, Our Perfect Wedding host and actress Nomsa Buthelezi and "Love Live Here" star Lungile Radu took to social media to wish Mandla well on his special day.
We're wondering if this was just a simple message or was it really something more? I guess they're happy to keep us guessing.
