“I can't wait to hear what my baby's voice sounds like ... lol ... I'm waiting,” Rob tweeted.

He got somewhat of a sneak preview on Wednesday when his ex Blac Chyna posted a series of videos of their daughter to Snapchat.

In the clips, Dream is blowing bubbles and adorably gurgling while bouncing up and down in her mom’s arms. The baby rocked a “Dessert First” bib and a precious smile.

“GOODnight my pretty baby,” Rob captioned several screengrabs from the clips.

Though Rob and Chyna are currently separated, the model and TV personality got candid about their relationship in her recent Cosmopolitan South Africa cover story.

“I'm in it for the long haul, so I feel like my advice [for anyone in a similar situation] is therapy, know each other's family, calling each other's moms,” Chyna told the mag. "I feel like everything isn't going to be perfect, but I know we love each other and we're fighting for each other, and the people we surround ourselves with are rooting for us. It makes everything much easier."
