By Bobbie Whiteman for MailOnline

They adopted a baby girl four years ago.

And on Thursday reality TV stars Scout Masterson and husband Bill Horn - best known as the 'guncles' to Tori Spelling's children - revealed that she now has a little brother.

The couple posted an adorable shot of the tiny tot's feet leaning against his sister, Simone's toes, and one of their somewhat bigger feet on their social media sites.

Scout, 39, proudly captioned his shot: '#TheGuncles fam is NOW 4! THRILLED to share the arrival of our son - Bosley Jo Masterson-Horn! #BabyBOZ.'

Bill, 42, added some extra information saying: 'Bosley Jo Masterson-Horn arrived early, but is a happy, healthy little boy! #BabyBoz #TheGuncles #Family #InLOVE'

The couple were regulars on Tori's reality show Tori & Dean, where they were affectionately known as The Guncles, merging the word gay with the word uncle, to Tori and Dean’s four children – Liam, Stella, Hattie and Finn.

The couple announced they were expecting their second child via Twitter on August 18 along with an adorable photo of Simone holding a picture of their soon-to-be little boy's sonogram.

'Our hearts are filled with joy — AND we're happy to say we're expecting,' the couple said.

They tied the knot after 10 years of dating at the Van Nuys Courthouse in July 2013.

Since wrapping Tori & Dean” in 2011, Bill and Scout have bowed their blog, GunclesOnline.com, and launched an adoption mentoring service charity, Hold My Hand. In 2012, Hold My Hand helped nearly 150 families with all areas of the adoption process, according to their blog.

The couple is involved with the non-profit Baby Buggy, which is dedicated to providing families in need with essential equipment, products, clothing and services for infants and children up to age 12.

Bill and Scout also run a boutique PR and marketing firm, Marque Communications, which specializes in baby and kids products and produces celebrity family events.
