Serena Williams and Novak Djokovic have been selected as the International Tennis Federation's world champions for 2014, ESPN reports. She participated in the Ultimate Run South Beach earlier this week, kicking off training for her 2015 tennis season.

The tennis star posted a photo on Instagram of herself with a caption reading "a fresh start," leaving many of her fans wondering if she was referring to her recent boyfriend and dating revelation.

Last month she revealed that she "desperately" wants to settle down and have children, mentioning that her "time will come."

The revelation spurred rumors about her break up with her rumored boyfriend Moruatoglou.

Serena Williams posted a photo on Instagram and Twitter several weeks back of a bottle of Château Lafaurie-Peyraguey wine with a caption reading "only you were missing."

The message left many of her fans wondering if it was about Moruatoglou.

She also uploaded a photo on Instagram and Twitter of herself having dinner by herself with a caption "dinner for one."

Serena Williams was recently spotted on a romantic date with him, the New York Post's Page Six reports.

"They seemed very intimate and they didn't stop chatting all night," an onlooker told the newspaper.
