Leo is the fifth of the twelve zodiac signs and is represented by the constellation Leo, the lion. 

 

If born under this sign, you're considered to be vivacious, outgoing and fiery.  And proud of it (along with your hair). 

 

Leos are known for their warm nature and high self-esteem, but on a bad day they can be a little haughty.  And sulk.  But get them back on stage, give a compliment or applause, and the big-kid lion is good to go again.
