Bill Clinton, the former president of the United States, is set to become a grandfather.
His daughter Chelsea is pregnant with her first child.
The former First Daughter, aged 34, made the big announcement during an event in New York on Thursday.
"Mark (Mezvinsky) and I are very excited that we have our first child arriving later this year..." Chelsea Clinton said.
"I just hope that I will be as good a mum to my child and hopefully children as my mum was to me."
Clinton and Mezvinsky married in 2010.
