Venus Williams was left wondering where her invite was after Serena Williams and Grigor Dimitrov hit the practice court together in Miami on Monday.
Dimitrov posted a video of himself hitting with Serena ahead of his appearance at the Acapulco Open in Mexico later this month.
The Bulgarian wrote: “My practice partner is better than yours."
The World No.17 added a ‘goat’ emoji in his caption, referring to Serena as the ‘Greatest Of All Time’.
While fans were delighted to see the two tennis stars in action on the court together, Serena's sister Venus couldn't help but feel a little jealous.
Venus commented on Dimitrov's video asking why she hadn't received an invite.
"Omg are you guys hitting now? Where is my invite??" Venus wrote.
It's not the first time Dimitrov and Serena (who were actually in a relationship for a brief period) have hit the practice court together.
In 2019 Dimitrov said the pair regularly train together after doing so at the Australian Open that year.
“It’s good to have those kinds of hits to be honest," he said.
"You can always learn a little something from whoever is on the other side of the net.
“We often hit actually, it just happened for everybody to be there that day.”
Dimitrov and Serena were romantically linked in 2012 before he moved on to Serena's fierce rival Maria Sharapova.
Ash Barty to miss Dubai event with injury
Meanwhile, Australia's World No.1 Ash Barty has withdrawn from next week's Dubai Tennis Championships as she continues to recover from a leg injury.
Barty, who also pulled out of this week's Qatar Open, struggled with a left thigh strain at the Australian Open before she went out in the quarter-finals.
"Unfortunately I have withdrawn from the Dubai Duty Free Tennis Championships," Barty said in a statement.
"I wish the tournament a safe and successful event and hope to play there next year.
"Thank you to the event organisers and the WTA for all the work you are doing.
She is now eyeing a return at the Miami Open, where she is the reigning champion.
"I look forward to competing again in Miami in a few weeks time," the 24-year-old said.
