'Heroes' stars end relationship

'Heroes' stars Hayden Panettiere and Milo Ventimiglia are said to have ended their relationship.

“It was a lifestyle conflict,” a source close to the couple told Usmagazine.com. “They were in very different places.”

Hayden, 19, who plays Claire Bennet on the hit US series, and 31-year-old Milo, who stars as Peter Petrelli, are said to have split in the last week.

“[Hayden] is young,” a source told the website.

“She likes to go out in the Hollywood scene and that’s not his style. (Milo) has been concentrating on work on his production company (Divide Pictures).”
