Hayden and Milo No Longer Making Pretty Nookie

Goodbye to you, Haylo.

Even heroes sometimes have to say goodbye.

Sadly, we have another breakup to report. This one may not produce the dangerous consequences of the Colin Farrell split (namely, Colin Farrell on the loose), but may pull at the heartstrings a bit more. Us magazine has confirmed that Heroes co-stars and off-screen lovahs, Hayden Panettiere and Milo Ventimiglia, are dunzo.

The split apparently happened last week, but the two are still on friendly terms. "There are no hard feelings," said a source close to the couple.

So what was the cause of the breakup? Different life phases. As in she's 19 and he's 31. "They were in very different places. She likes to go out in the Hollywood scene and that's not his style."

What's a man to do? She's young, carefree, likes to wear a G and carry a fake ID. It's a tale as old as time. But don't worry, Milo. A few hours alone with Colin and she'll come running back to you.
