Rob Kardashian is looking forward to the day where he can talk to his daughter. His infant daughter may only be 4 months old, but Rob revealed that he's already anxious for her to start talking. "I can't wait to hear what my baby's voice sounds like," he tweeted on Wednesday. Good news for the 30-year-old reality star ? Dream appears to be just as excited to find her words, too. Rob's ex-fiancée Blac Chyna shared Snapchat videos of their little one cooing happily on Wednesday while nestled in Chyna's arms.
