Tennis legend Novak Djokovic’s marriage is under scrutiny after wife Jelena — his “rock” — missed his Wimbledon win.

The 33-year-old did not attend any of his matches at the tournament in which he beat Roger Federer in last Sunday’s final — his fifth men’s title victory. She also missed the prestigious Wimbledon Champions Ball, leaving him to go alone.

It sparked questions about the pair’s five-year marriage, as Jelena almost always sees him play.

After last year’s win, she posted: “Thank you amore for bringing us so much joy.”

This year, Djokovic, 32, said his wife had been at their London home with their daughter, Tara, 1. They also have a son, Stefan, 4. He said Tara was too small for Wimbledon — but Jelena was comfortable leaving her at home so she could attend last year.

The Serbian couple’s marriage has previously been hit by rumors of his alleged infidelity.

They failed to mark their July 10 anniversary on social media this month after last year posting a snap together that she captioned: “Love loving you my love.”

A source said: “Jelena has always been Novak’s rock but there is speculation that they could be having problems.

“To not attend a single Wimbledon match is quite a statement for someone usually so quick to share her pride in his success and how strong they are together.”

After his victory, Djokovic said: “It’s extra special sharing it with my son in the crowd and my parents, the whole team. My wife and my daughter are here in London, but they’re at home. So I give them a big, big hug.”

A day earlier, Jelena Djokovic posted a picture on Instagram of her children with the location marked as “Wimbledon.”

Sunday night, after a long period of silence, Jelena posted an Instagram story showing the couple reading coverage of her husband’s Wimbledon win.
