The retired Olympic heptathlete announced her pregnancy back in May this year, in another photo featuring Reggie - who, it seems, won't be feeling left out! - clutching a book entitled "I'm going to be a big brother".
"Someone's going to be a big brother! Another little Ennis-Hill on the way. So happy."
Jessica, who won gold at the 2012 Olympic Games in London for Great Britain.
After having her son, Reggie, she then went on to win a silver medal in the 2016 Rio Olympics, before retiring from professional sport the following October.
She announced on Instagram at the time: "This has been one of the toughest decisions I've had to make. But I know that retiring now is right. I've always said I want to leave my sport on a high and have no regrets and I can truly say that."
Since then, she has founded music and running festival Vitality Move, which is dedicated to getting a wide range of people involved in running.
