Serena Williams mentioned on Facebook that she is thankful for having coach and rumored boyfriend Patrick Mouratoglou's "continued help and support."

"we did a great job this week. Picking up where we left off. I'm still hungry. Let's keep it up. Thanks for your continued help and support! U ready???" she posted in a tag.

"am I ready ? what do you think?" the French tennis star responded.

Serena Williams' coach and rumored boyfriend Patrick Mouratoglou posted photos of her training at Melbourne Park for the Australian Open just after Serbian tennis star Jelena Jankovic mentioned she can "beat her."

"Last week preparation starts tomorrow to get ready for the #AustralianOpen main draw," he wrote in one post on Twitter."

Earlier this week, Jankovic told reporters she could hold strong against Serena Williams.

"I think I'm one of the few players who has lots of wins against her and her sister," Jankovic said, according to the Sydney Morning Herald.

"When you step on the court, you don't have to think that it's Serena out there. If you were able to beat her in the past, you can do it again. That's my mentality and that's how I always play."

Serena Williams and Maria Sharapova have showed no signs of thawing in their cold relationship as the Australian Open continues, leaving many fans wondering if coach and rumored boyfriend Patrick Mouratoglou will be caught in the middle.
