Caitlin Clark’s fame knows no age limits.

While appearing at the Indiana Fever’s Fever Fore Change golf event Thursday, the WNBA All-Star not only met a 2-week-old baby — but signed her onesie.

“Hey, we have the biggest fan!” the baby’s mom joked.

“Is this the youngest [fan] to get an autograph?”

When asked if that was the youngest person to ever receive her autograph, Clark concurred.

“I think so,” the 22-year-old guard said with a laugh. “I signed an ultrasound one time. But yeah, actual living in the world, yes.”

From there, Clark, her Fever teammates, the baby and the infant’s mom all posed for a photo.

After having nearly a month off due to the WNBA All-Star Break and the 2024 Paris Olympics, Clark and the Fever return to the hardwood Friday night against the Phoenix Mercury.

Through her first 26 pro games, Clark has posted 17.1 points, 5.8 rebounds, 8.2 assists and 1.5 steals per game.

She was named an All-Star but not selected for the women’s national team — which took home its eighth straight gold medal at the Paris Games.

Clark and Team WNBA actually downed the Olympians, 117-109, in the modified All-Star Game format as the rookie notched four points and 10 assists in Phoenix earlier this summer.

Despite playing in the game and attending All-Star week festivities — even donning a necklace that has a value greater than her base salary — Clark seemed to relish having time to relax after a grueling college season and little reprieve heading into the WNBA.

The former Iowa star met Aaron Judge at a Yankee game on Aug. 9 and attended a Jordan Davis concert in late July. She also relaxed on a boat with loved ones.

Despite boasting Clark and former No. 1 pick Aliyah Boston, the Fever sit at 11-15 through the first half of play.

Clark and the rest of her squad have 14 games remaining to get into playoff contention, something the Fever organization hasn’t done since 2016.
