There are a couple of grammatical problems with the question. "Hablando" is the gerund form of the verb "hablar", meaning "to talk" or "to speak". This is usually not used by itself, but rather combined with a conjugated form of "estar". This forms the "progressive" tense, and is used for action that is occurring at the present moment. "Estoy hablando" is "I am talking".
"Nicest" is not a Spanish word. There are several ways you could espesss this concept. One is to use "más simpática".
With this in mind, the sentence should be "Estoy hablando con la chica más simpática en el mundo." It means "I am speaking with the nicest girl in the world".
La unica chica para mik = The only girl for me su amigo = his/her/your (male) friend sabes que estoy hablando = know what I'm saying
"...that talking to my...."
It means that you like talking.
