Djokovic's wife appears with growing baby bump

Rumors swirled in February that Novak Djokovic's wife Jelena was pregnant, and though neither have verbally confirmed it, Jelena is courtside in Monte Carlo with an unmistakable baby bump. This update comes hot on the heels of Serena Williams' pregnancy news.

Despite efforts to conceal it, lady Djokovic appears to be a few months along.

The Djokovics welcomed their first child, a son named Stefan, in 2014. According to Serbian tabloid newspaper Blic, they have always wanted to have two children.

Djokovic is the No. 2 seed in Monte Carlo and has advanced to the quarterfinals with a three-set win over Pablo Carreno Busta.
