Hayden Panettiere has reportedly admitted that there is an "expectation" that she will become the "next party girl".

According to Just Jared, the 20-year-old Heroes actress told the latest issue of Self that she was aware of the typical image associated with young celebrities.

"There's an expectation for me to be the next Messed-Up Party Girl. But I just focus on living my life, being myself and doing what I love," she is quoted as saying.

Panettiere also spoke about recently joining a protest against whale and dolphin killing, saying: "I left knowing I'm not going to let those dolphins die in vain. Their deaths will help show the world the big picture."
