Serena Williams and Maria Sharapova were spotted snapping photos together at the Women's Tennis Association's '40 Love' party last weekend, raising rumors that the two tennis stars are making amends after a recent spat over Grigor Dimitrov and their relationships.

The Wimbledon star and Maria Sharapova were joined by a number of their fellow tennis pros and legend Billie Jean King, according to Sports Mole.

Serena Williams, who was knocked out of the Wimbledon 2013 after Sabine Lisicki ended her winning streak on Monday, personally apologized to Maria Sharapova about her recent comments two days before the Russian tennis star retaliated with her own thoughts, the New England Sports Network reports.

"If she wants to talk about something personal, maybe she should talk about her relationship and her boyfriend that was married and is getting a divorce and has kids," Maria Sharapova told reporters, responding to Serena William's initial comments about her relationship with Grigor Dimitrov, her ex-boyfriend.

Maria Sharapova was targeting Serena William's relationship with coach and rumored boyfriend Patrick Mouratoglou.

But Serena Williams also made blunt comments about Maria Sharapova's personal life and tennis career.

"There are people who live, breathe and dress tennis. I mean, seriously, give it a rest," Serena Williams said in a recent interview, indirectly referencing Maria Sharapova.

"She begins every interview with 'I'm so happy. I'm so lucky' - it's so boring. She's still not going to be invited to the cool parties. And, hey, if she wants to be with the guy with a black heart, go for it.

Both Serena Williams and Maria Sharapova have not commented on the spat since its onset.
