Hayden Panettiere's BRO gives his SEAL of APPROVAL on MILO!

Us Weekly reported in January that Milo Ventimiglia has the stamp of approval from Hayden Panettiere's mother – and now he has the OK from her 13-year-old brother.
"Milo is cool, he's a pretty chill guy," Jansen Panettiere told Usmagazine.com at the Alvin and the Chipmunks DVD release party in L.A. Thursday.
Panettiere, 18, and Ventimiglia, 30, have been dating since last year.
Us had reported that Ventimiglia had a crush on his Heroes co-star since she was dating Stephen Colletti. Ventimiglia 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.
Said the source, "[Hayden] is really like a 30-year-old."

Do you think Hayden and Milo will last?
