Christmas has come early for the Sebastians, with the gift of a new addition being bestowed upon the close-knit family.

Jeremy Sebastian – who is the brother of Standing With You singer Guy Sebastian and The Voice winner Chris Sebastian – has welcomed a son with his wife Emma.

Taking to Instagram, the youngest Sebastian brother Jeremy, 30, revealed the happy news and shared the gorgeous first pictures of his new bundle of joy.

“Welcome earth side my little legend. Fergus Richie Xavier,” he wrote, before praising his partner, adding: “Well done wife, you nailed it”

Included in the photos were details of the birth, with a card revealing the baby was born at 5.25pm last Thursday in Adelaide and weighed 3460gm.

The Voice coach Guy and his fashion guru wife Jules couldn’t wait to share their delight at the announcement of a new family member

“I’m dying to see him,” Guy, 39, gushed.

Jules added: “The love is deep. My babies had a BABY. Love all 3 of you.”

Last week Chris, 32, revealed his excitement about the impending arrival of Jeremy’s baby during an interview with WHO.

“My younger brother is having a baby tomorrow,” Chris spilled last Wednesday.

“So Christmas this year is going to be an extra special one. I’ve got an eight-month old [daughter Ava] so it’s her first Christmas. And then yeah, Jeremy my younger brother will have a baby tomorrow. That will be the sixth grandchild for Mum and Dad.”

Jeremy, Chris and Guy also have an older brother called Ollie, 42, and all four siblings are well-known to be tight-knit.
