The Block's billionaire buyer Adrian Portelli has shared an exciting announcement, revealing he and his girlfriend Karlie Butler have welcomed a baby boy.

Taking to Instagram, Adrian shared several snaps of himself with his son, writing, "Welcome to the world little man."

Speaking to the Herald Sun, Adrian shared that Karlie gave birth on Monday, saying, "He was four days over ... it’s an amazing, overwhelming experience."

In November, he gave Karlie an Aston Martin as a 'push present', writing on Instagram, "Push prezzie well deserved for putting up with me."

Adrian has been holding online raffles for people to win the houses he purchased on the show, with the winners able to choose between cash or the house.

Eliza and Liberty's House 5 was recently raffled off, with the winner able to choose between $2.2 million or the $4.3 million house.

However, the girls were forced to issue an apology after the winner announcement.

Adrian called the winner, Shane from Victoria, before passing the phone to the sisters so they could break the news.

“Now, you didn’t win the third prize, you didn’t win the second prize,” Eliza teased. “So I guess that means - you’ve won first place!”

Eliza and Liberty both screamed the announcement into the phone which affected their microphones and caused the audio to cut out.

It wasn’t until after the Facebook Live ended that the fan favourites realised their mistake and posted a “formal apology” on their Instagram Story.

“I would like to issue a formal apology to the LMCT+ staff, to the LMCT+ community, to Lib and Adrian,” Eliza began. “I screamed in the giveaway and it turns out the loudness of my voice, the decibels, has knocked out all the microphones because it's never heard such a high decibel!”

“So in turn that meant that no one could hear the winner announced,” Liberty added. “So congratulations, you have ruined the winner announcement, how do you feel?”

“I genuinely ruined everything and I actually feel terrible,” Eliza replied.
