According to this tweet Derek Watts sent on May 30, the Princess of Monaco is expecting twins.
This has not been confirmed by the palace's press office. Charlene will not be accompanying Prince Albert to the Netherlands.
"My old bulawayo schoolmate mike wittstock has phoned to say his daughter is pregnant with twins. Congrats princess charlene and albert!"
The local newspaper also spoke with Charlene's father, who stated his daughter is pregnant with twins.
I would not call the comments about twins to be gossip, as it was Charlene's father who made the statement.
The official announcement did not say the Princess was having a baby. The palace announced a pregnancy, thus avoiding, for now, the idea that Charlene has two buns in the oven.
