Jimmy Kimmel has a new daughter.

That kind of sounds like he's replacing the old one.

Kimmel and wife Molly McNearney have welcomed a baby girl into the world, Kimmel tweeted Thursday, writing, "Congratulations to my beautiful and very tough wife @mollymcnearney on delivering our baby girl this morning."

McNearney is the co-head writer of "Jimmy Kimmel Live."

Kimmel also tweeted, "Thanks for all your kind baby wishes -- turns out, not ALL tweets are mean!" Kimmel was referring to the regular segment of his show, during which celebrities read nasty things people write about them on Twitter.

The couple married last July. Kimmel has a son and daughter with his previous wife, Gina Maddy.
