What did young “Hereos” hottie Hayden Panettiere want for her 18th birthday? A tattoo to show the world her love of astrology and her sign Leo, of course. The blond starlet let the cat out of the bag recently, telling a reporter, “It’s a Leo symbol on my ankle. My mom didn’t see it for ages.” Leos are outgoing, energetic, creative, determined, and seem to make a splash everywhere they go. Nice to see that while she is basking in the glow of the spotlight she remembers to thank her lucky stars.
