According to Us magazine reports, the chronologically challenged pair, Hayden Panettiere, 19, and Milo Ventimiglia, 31, her 'Heroes' co-star, have ended their relationship, due to 'a lifestyle conflict. They were in very different places.'

While, he was 'concentrating on work', she 'likes to go out in the Hollywood scene,' and RadarOnline reports on its website, she was also spotted 'sitting in Jesse McCartney's lap,' at Crown Bar in Los Angeles last week, as the 21-year old pop singer kissed her neck, 'Then she got up and did some crazy sexy dance in his lap.'

The 12-year age gap between Panettiere, 19, and Ventimiglia, 31, may be a major factor for the split, however, the two continue to remain on friendly terms, with no hard feelings.
