meaning - What does 氏 mean after a name, how is it different from さん or 様?

If you look in the dictionary for the definition of 氏 you'll find it defined as: family name; lineage; birth.

However I have seen it used in such a way that it is doubtful that it means any of those things in certain contexts.

Here's an example sentence:

今日はマオ氏のアーバンカーで送ってもらった♪(´ε｀ )

What does 氏 mean here?

Note: Mao is a very famous Japanese singer.
