The 'Keeping Up With The Kardashians' star opted for the unusual moniker for his little girl - who he has with Blac Chyna - as it has always been a "dream" to have a child of his own.

A source told Us Weekly magazine: "Dream was Rob's favorite name because it was always his dream to have a baby. She is gorgeous and looks a lot like Rob!"

Meanwhile, Rob and Chyna are said to be in a "great place" since the birth of their child, who they welcomed into the world on Thursday (10.11.16).

An insider said: "Rob was so supportive of Chyna. He was encouraging her and being so sweet.

"Everyone was so touched by how emotional he got ... Rob and Chyna are so happy. They're in a great place. The plan is for the baby to come back to Chyna's - Rob will be there too. He is already in love with his daughter."

Rob took to social media on Thursday to share his excitement at Dream's arrival.

He wrote on photo sharing site Instagram: "Today was amazing. I am so lucky!! Thank you @blacchyna for having our baby and being so strong!

"I love you so much and can't wait to see her get older day by day with you Chy! I love you and Dream so much and Appreciate both of you. I know everyone saying that's my twin but that's def your nose Chy lol (sic)"

And despite only being a couple of days old, Dream has already made her first post on social media.

Updating microblogging site Twitter, her mother Chyna shared a picture of the little one breastfeeding, captioning it: "Morning. Bonding time with mommy."
