This guy is winning over the fam.
We reported in January that Heroes star Milo Ventimiglia got the stamp of approval from Hayden Panettiere's mother, Leslie Panettiere.
Now he has the OK from her 13-year-old brother, Jansen Panettiere.
"Milo is cool, he's a pretty chill guy," Jansen Panettiere told Us Weekly at the Alvin and the Chipmunks DVD release party in L.A. Thursday.
Hayden Panettiere and young Jansen Panettiere are both actors!
As you surely know, Hayden Panettiere, 18, and Milo Ventimiglia, 30, have been dating since last year, following a long string of denials that they were dating.
Ventimiglia had a crush on his Heroes co-star since she back when she was dating reality star and VJ Stephen Colletti. That ended last summer sometime.
Milo confessed it "the minute she broke up with Stephen," a source said.
A source close to the actor shrugged off their 12-year-age gap between the two hotties, saying, "[Hayden] is really like a 30-year-old.
Please, don't say that, source. You're killing us.
