After Prince Laurent and Princess Claire (of Belgium), Crown Prince Frederik and Crown Princess Mary of Denmark are expecting the second set of royal twins of the past few years in January of 2011.

Speculation about Princess Mary being pregnant have been running for a while now, but today the Danish court confirmed it on its website. As the children are due in January, she’s passed the third trimester of gestation, unless they’re not planning on a whole 40 week pregnancy, but that’s speculation.

I can’t say I’m exactly thrilled about this.
