Jared Padalecki Baby's Name and Photo Released

Jared Padalecki and his wife Genevieve Cortese announced the name of their son along with a photo nearly a month after the baby's birth this week.

The "Supernatural" co-stars welcomed their second child on Dec. 22, but waited until now to share extra details on Twitter.

"Ok. There it is, my wife @realGpad just revealed Tom's little brothers name. Here goes," Padalecki tweeted on Jan. 21.

Later, Cortese added, "@jarpad and Shepherd watching some late night #supernatural."

The couple is also parents to 22-month-old son Thomas Colton.

Both actors who met while filming "Supernatural" together, Padalecki and Cortese married in Sun Valley, Idaho in Feb. 2010.

The happy couple announced the arrival of their second child on Christmas Day.

"My amazingly strong wife home-birthed a happy and healthy baby boy last night," Padalecki wrote to his followers. "Please send love."

In having a home birth, Cortese joins thousands of other women who elect a non-clinical setting to welcome newborns. Home births are often assisted by a midwife and have gained popularity in recent years.

Following baby Shepherd's arrival, Cortese thanked her legions of "Supernatural" fans for their congratulations.

"Thank you so much for all of the well wishes!!! The Padalecki's wish everyone a Happy New Year," she wrote.

Then, weeks later, the starlet explained her absence from Twitter on Jan. 9.

"This is a little late but thank you for the birthday wishes," she tweeted to her fans. "Been in baby hibernation."

The actress also wrote, "A baby at 31, a baby at 32, What's 33 gonna bring?!!"

Padalecki joins several other actresses in Hollywood who are expanding their families this year.

In fact, fashion designer and reality television star Rachel Zoe also welcomed a baby son on Dec. 22.

"As loyal readers of The Zoe Report, I wanted you to be the first to see a picture of the beautiful new addition to our family, Kaius Jagger Berman, aka "Kai," the 42-year-old mother wrote.

The new baby joined big brother Skyler, 2.

Furthermore, Emily Blunt, Kerry Washington and Drew Barrymore are all expecting babies in the near future.
