“I felt so old” – Andre Agassi and Steffi Graf’s daughter Jaz ringing in her 21st birthday leaves Serena Williams’ ex-coach reeling in shock

Andre Agassi and Steffi Graf’s daughter Jaz recently celebrated her 21st birthday with a fun party. The occasion left Serena Williams’ former coach Rennae Stubbs astonished by how quickly Jaz has grown up. Agassi and Graf, who tied the knot in 2001, have two children together. Their son Jaden was born the same year as their wedding, and they welcomed their daughter Jaz in October 2003.

Jaz turned 21 earlier this month, choosing to celebrate her birthday with a night out in Las Vegas. Her brother Jaden’s girlfriend Catherine Holt documented the festivities on social media, sharing a glimpse of the birthday girl dancing and celebrating joyfully with her friends.

Coincidentally, Rennae Stubbs was in Las Vegas on the same day to cheer on the New York Liberty in their WNBA playoffs semifinal against the Aces. During a phone call with Steffi Graf, Stubbs learned that Jaz was ringing in her 21st birthday that evening, which left her reeling in shock and feeling “so old.”

“Her daughter just turned 21. She texted me, we were texting the other day and I was like, ‘Wait! What?’ Because I was in Vegas at the same time, I went to watch Liberty beat the Aces. And she’s like, ‘Jaz is having her 21st birthday tonight.’ I was like, ‘What? She’s 21?’ Oh my god, I felt so old in that moment,”
