Question about twitter?

[XxStephanie]

Okay, so I'm new to twitter and just have a few questions about the posts I keep seeing:
1. I'm following a few celebrities and when I go onto their accounts there are always several post that begin with @ThenTheNameOfRandomObsessedFan#7482910 and I was just wondering if these posts were From given celebrity or it they are from obsessed fan #7482910??
2. When you see a #ThenAFewWords what does it mean??
Thanks for helping make my Intro to twitter just little simpler

I don't understand the first question.

The second: It's called a hashtag, here's the page in the Twitter Help Center: https://support.twitter.com/entries/4930...gs-symbols
