Steph Curry may be known for sinking threes … but, ya gotta think four’s his new favorite number — ’cause he just announced the birth of his fourth kid!

The Golden State Warriors star took to Instagram to tell his followers he and his wife Ayesha added a little one to their roster … posting a black and white photo of what looks like his hand wrapped around his baby boy’s tiny arm.

Curry says his son decided to come a little earlier than expected … adding he was born May 11 before noting he’s happy, healthy and settling into their new family of six.

Steph announced his baby boy’s name too — Caius Chai Curry … definitely sensing a theme there.

It may seem like a whirlwind pregnancy for some fans … after all, Ayesha only announced she had a bun in the oven back in March — revealing it in a cover story for the magazine, Sweet July.

She told the publication she and Steph thought they were done having children after their third kid was born in 2018 — but, made the decision to try again last year.

Anyhoo … congrats on adding your Sixth Man, Currys!!!
