Rumour has it that actress Boity Thulo is dating 'Vuzu' presenter Siyabonga Ngwekazi.

The duo threw a joint birthday party at Taboo in Sandton recently, despite the fact that their birthdays are a whole month apart, and the two reportedly got very cosy as they partied the night away with fellow celebrities such as Pearl Thusi and Sizwe Dhlomo.

According to Drum magazine, sources claim that Boity and Siya have known each other for a long time, but that their friendship recently evolved into a relationship.

"Siya and Boity are so cute together, they're totally in love," an insider revealed to the publication.

"They've been good friends for many years, but they've taken their friendship to the next level; they spent the night cuddling and laughing together."

The 24-year-old 'Rockville' actress, however, nervously denied that she's dating Siya when approached for comment.

"How did you find out about this? Is it because of the party?" she said.

"Siya and I aren't dating, we're just good friends and we're find just the way we are. If you want to know anything else, call Siya and ask him."

But the 32-year-old TV presenter's phone reportedly just rang unanswered when Drum phoned him for confirmation.
