Heroes actor said to have chosen a Cartier ring for her

Milo Ventimiglia plans to pop the question to his girlfriend Hayden Panettiere.

And the Heroes actor, 31, is going all out to impress his 18-year-old co-star.

‘He was looking at rings and really likes Cartier — he intends to spend $200,000 [£100,000],’ a source tells The Sun.

Milo and Hayden are currently looking for a house together in LA.

It is thought he will propose later this year.
