Ryan Murphy
must be full of "Glee!"

The "Glee" and "American Horror Story" creator shared a picture of his one-week-old baby boy, Logan Phineas Miller Murphy, via twitter on New Years Eve -- and we have to say the little guy's resemblance to his famous father is incredible!

This is the first photo we've seen of the fair-haired cutie. Logan was born on December 24, 2012 at 9:47 am, weighing 6.6 pounds and 21 inches tall.

Murphy tweeted, "Thanks to everyone for the kind wishes. Logan is one week old and doing great. Happy new year!," along with the picture.

This is the first child for Murphy and his husband, photographer David Miller, who wed in July after two years of dating.

We can't wait to see more pictures of little Logan -- check out even more celeb TwitPics in the gallery above!
