The 26-year-old rapper split from the busty model in 2014 following three years of on/off dating but he's thrilled for her and her fiancé Rob Kardashian and can't wait to meet their little girl.

A source told the HollywoodLife.com: "No doubt Tyga and Chyna have had their ups and downs, but he's crazy excited for her and Rob and can't wait to meet the baby."

The 'Rack City' hitmaker - who is now dating Rob's half-sister Kylie Jenner, 19 - has four-year-old son King Cairo with Chyna and is interested to see if Dream looks like his child.

The insider explained: "He's anxious to see how close their daughter will resemble King Cairo.

"Tyga is tired of King bouncing off the wall with excitement, anticipating his sister's birth, and wanting to meet her like a kid waiting to open gifts on Christmas Day."

Dream - the first child for Rob and Chyna - took her first breath on earth at 9:18 am (PT) and weighed a healthy 7 lbs. 5 oz.

Chyna and her 29-year-old beau are paying $4,000-a-night to stay in a luxury maternity suite at the hospital, where Rob's famous sisters Kim Kardashian West and Kourtney Kardashian have previously given birth to their children.

The new parents - who have been together since the beginning of this year - were initially hoping to capture the birth on camera to air in a baby segment of their reality TV show 'Rob & Chyna'.

But the couple reportedly ran into some trouble when the camera crew bounded into the maternity suite today, as the hospital have a protocol in place that prevents anyone from recording on the premises, according to gossip site TMZ.
