He’s here — ahead of schedule!

Bill Horn and Scout Masterson welcomed their second child earlier this week, the couple announced Thursday on social media.

Bosley Jo Masterson-Horn arrived early, but is a happy, healthy little boy!” Horn, 42, captioned a sweet snapshot on Instagram.

The new dads shared a photo of their son’s tiny toes cuddling with big sister Simone Lynne‘s feet.

Masterson, 40, posted the same picture on Twitter, writing, “#TheGuncles fam is NOW 4! THRILLED to share the arrival of our son – Bosley Jo Masterson-Horn.”

Their newborn’s name holds special meaning for the couple, who chose to skip the baby books and made their decision based off inspiring moments throughout their journey to a second child.

“We’re so thrilled that our son, Bosley Jo, has arrived! When we heard the news [that we had been chosen by a birthmother], we were laying in bed watching Elementary, and that night, there was a character named Bosley,” Masterson tells PEOPLE.

“I said to Bill, ‘Bosley! I think that just sounds right. It feels like our son.’ We decided it was the top choice, and we texted our BFF Tori [Spelling] to see what she thought of the name. She immediately said something like, ‘I love it. So chic and like Charlie’s Angels.‘ Ha! It didn’t occur to us … But that made it even more perfect! And Boz or Mr. Boz are his nicknames. Simone calls him Baby Boz.”

As for their son’s middle name, the couple chose a moniker “in honor of a very dear, best friend of ours,” who passed away from cancer. According to Masterson, she was a strong supporter of their decision to expand their family further.

“JoAnne (‘JoJo’) was like family to us, and exactly two weeks younger than me. She was in our everyday lives and she knew how long we waited for Simone,” he explains. “She knew we wanted to have a second child — always saying that someday soon it would happen for us.”

And although she died before Masterson and Horn knew they would be welcoming a baby boy, JoJo and Bosley already share a special connection.

“Bosley was born in the same town that JoJo passed. We know in our hearts that JoJo sent little baby Boz to us via his amazing birthmother,” Masterson says. “This all happened so quickly — we know a sign when we see one — and this is DEFINITELY a sign!”

In August, the Extreme Guide to Parenting stars announced their plans to expand their family and were looking forward to seeing 4-year-old Simone step into her role as big sister.

“Simone is so excited about being a big sister and both Scout and I are only children, so we’re thrilled about being able to give her the gift of a sibling,” Horn told PEOPLE at the time.

Congratulations to the daddies and new big sister! What a lucky baby boy to have so much love.

Erin on

So precious. I wish their lovely family much love and happiness. Have to admit, I tend to forget their last name isnt Guncle lol.

Heather on

Congratulations! I never get it when people do this type of pic. We don’t want to see daddy’s feet. We don’t need the reference, we know baby feet are tiny! The baby feet are cute though.

Shirley on

OK…sorry to be out of the loop, but who are the Guncles?

Julie on

Interesting… a lot of homophobes must have read the article with all the mad faces. Guess what bigots… GET OVER IT!!

Congrats!

Erin on

They are close friends to Tori Spelling – she refers to them as Guncles – gay uncles.

CC on

They seem like wonderful parents to their daughter, so there is no doubt that this boy will have a wonderful life ahead of him. Congrats to this sweet family.

Congrats to the family! Bill and Scout always seemed like such a great couple, I’m sure they’re wonderful parents too.

Congrats! Not sure about the name Bosley. It’s definitely unique, but reminds me of an old man, or Bosley from Charlie’s Angels.

Callie on

I wonder which one produced the egg and vagina to have this baby.

TK on

Jo is the female spelling Joe is the male spelling. Just saying. He already has 3 last names could spell the only first name manly. Love the two kiddos feet together. Congratulations to them all.

God bless you all!

Maryah on

OMG I seriously thought one of the guy in Heroes !!! lol congrats to the daddies and the big sisters.

Sadly for those who complain, I just read about a woman and his boyfriend who left their precious newborn on a gas station restroom… =( those are really bad news, not this, this is pure love and joy.

HJ on

Odd, no one knew who these guys were before Tori Spelling had them on one of her shows. Then they both are on a show about parenting their daughter (horrible episode, true helicopter parents) and now….another baby! Does he resemble a Spelling?

whyaretheyhere on

Congrats…but seriously, these are friends of a somewhat famous person. Why are they even on here?

nikki on

Don’t like his name, but congrats

Alissa on

Sweet story about how they found the name for their son.

A baby is always a blessing and this baby in no different. No one is being helped/served/saved by comments about this couple’s relationship. As a Christian, I have my beliefs and I try to uphold them, but as a Christian, and a person, really, I know, and fully accept, that not everyone has the same beliefs or even makes the same choices.

Congratulations to the parents on the wonderful blessing of a child.

Val on

Congrats to them for the new addition.

Nikki on
