Cam Newton has a new reason to celebrate.

The Carolina Panthers quarterback and his longtime girlfriend, Kia Proctor, welcomed a baby boy to their family last week. The NFL MVP favorite announced the news Wednesday on Twitter.

The baby boy was born on Christmas Eve, sources told ESPN’s David Newton, which explains why the QB left practice early that day. It also explains why Cam Newton dropped his signature dab in favor of a “rockin’ the baby asleep” touchdown celebration during the Panthers’ loss last weekend.

Newton also tweeted an explanation for why he waited to announce the news.
