The former US president is set to become a grandfather – his daughter Chelsea is pregnant with her first child.
The 34-year-old announced the news at a lavish event in New York City on Thursday.
“Mark and I are so excited to be expecting our first child, who is due at the end of the year. I hope I can be a great mother to my child and I hope I can be to my child what my mother was to me,” Chelsea said.
