Isaiah Fisher is the gift that keeps on giving.

Carrie Underwood’s brand new baby boy was the center of a hashtag when she tweeted about her birthday on Monday night (March 9).

She still hasn't posted a full photo to corroborate that description of her son, so we're just going to have to take her word for it.

She quickly followed up that tweet with a random connection to Chuck Norris. Again, her birthday presents just never stop coming.

Even her husband Mike Fisher got in on the birthday tweeting.

Making him, obviously, the early favorite for husband and father of the year.
