Hailey Bieber is basking in her baby’s milestones.

The model shared that her and Justin Bieber’s 16-month-old son Jack Blues Bieber is not only speaking, but that he has a favorite word he can’t get enough of. 

“He says ‘basketball’ all the time,” Hailey said on the Feb. 18 episode of the Therapuss With Jake Shane podcast. “I went to get him up from his nap today, and he was like ‘basketball’. It’s insane. So funny.”

And that’s not all. Hailey—who married Justin in 2018—also noted their baby boy has good manners.

“He also just started saying please,” she revealed. “He knew how to sign please for a really long time. So if I would say, ‘Hey, say please’, he would go this,” she said as she held up the American Sign Language term. “As please.”

But Jack isn’t just signing, he’s also singing. Indeed, the Rhode Beauty founder shared her son is taking a page out of Justin’s book and loves to sing his dad’s hit “Baby.”
