"She wants nothing but perfection for her big day, which is why everything will be done her way," said the pal.
Another friend said the 29-year-old actress' wedding will take place in a few weeks at an undisclosed venue in Joburg.
"Being the very private person that Dineo is, she's keeping things as quiet as possible because she wants to surprise everyone and doesn't want to be predictable."
The couple will also have a white wedding ceremony later in the year, the friend said.
"She's pulling out all the stops for her white wedding as well. We all know she loves fashion, so she's making sure that she is the talk of the town. She is making sure to give very specific instructions to the designer as to how her dress should look like."
A third friend said both the couple's families are over the moon about the pair's upcoming nuptials because the couple has been through a lot together.
"It's very rare to find relationships that last this long in the entertainment industry because there's so much going on and people's egos sometimes get in the way of their relationships.
"But Dineo and Solo proved that a relationship can work despite the fact that they are both in show business. Their love for each other is unwavering, which is why they both have the support of their families," said the bud.
Moeketsi said: "Me? Getting married, I wish I was getting married, who told you that? My love, I so wish I was getting married."
Her man also gave us the run around.
"My man, you are going to have to call me much later, because I'm shooting at the moment."
