Hayden Panettiere, 19, and Milo Ventimiglia, 31, have broken up last week due to “lifestyle conflicts”.

An insider close to the couple tells Us magazine that Ventimiglia "has been concentrating on work on his production company [Divide Pictures]" while Panettiere "likes to go out in the Hollywood scene and that's not his style."

Hayden Panettiere was reportedly seen kissing the 21-year-old singer/actor Jessie McCartney earlier this month.

So, the two Heroes co-stars separated just because of lifestyle conflicts? :-)
