Milo Ventimiglia spotted ring shopping for girlfriend Hayden Panettiere

In Touch magazine claims that Heroes actor Milo Ventimiglia, 31, is going to ask girlfriend and co-star Hayden Panettiere, 18, to marry him. The couple haven’t been publicly dating all that long, since Hayden only became legal last August. But it was widely rumored that they were together for a while before that. If she wasn’t so young, I’d probably say they seem cute and happy together, best of luck, etc.

Don’t tell Hayden Panettiere, but her boyfriend, Milo Ventimiglia, is planning to propose! The actor, 31, recently confided to a friend that even though Hayden is only 18 years old, he wants to get engaged, preferably this year. “Milo was looking at rings in late June,” the pal says. “He really likes Cartier and intends to spend around $200,000.” Hayden and Milo, who met on the set of Heroes, reportedly began dating in January.

I think January is when they actually kinda sorta acknowledged that they were seeing each other. I will admit that Hayden seems a lot more mature than most of the other girls her age in Hollywood. You don’t see her out tramping around like Paris/Britney/Lindsay. She goes out to dinner and shops and does all that other photographer-friendly stuff, but she’s never photographed falling out of clubs drunk, and I’m pretty sure she has yet to rack up any DUIs.

All that said, she’s still 18. Being more mature than Paris Hilton doesn’t make a person ready for marriage. If so, my cats could have gotten hitched years ago. 18 is still 18, and that’s damn young to commit your life to someone, no matter how great they are. I doubt Hayden’s had all that many boyfriends besides Milo. It makes sense that he’s probably ready to get married at his age, but even if she thinks she is, it’d probably be best if they gave it some time. Maybe he’s just getting her a promise ring or something else more age-appropriate.
