Chelsea Clinton has just announced that she’s pregnant with her third child with husband Marc Mezvinsky. The two already have 4-year-old Charlotte and 2-year-old Aidan. 

“Marc and I have loved watching Charlotte be such a wonderful big sister and we’re excited to watch Aidan become a big brother!” she wrote on Twitter. “We cannot wait to meet our newest addition later this summer.”

Neither can we!
