is moving out of her parents' home and into her own crib, but her boyfriend
, Milo Ventimiglia
, isn't celebrating.
Why is Milo in the dumps? Well, he thought he and his 12-years-younger Heroes
costar would buy a home together!
"They were looking, and then Hayden suddenly bought this $2.6 million house in West Hollywood," says a pal of the actress. "He isn't happy."
But it turns out Hayden isn't ready to play house. According to the friend, she's "freaking out" because Milo keeps talking marriage. Adds the chum, "She's not even old enough to have a drink, so she's not even thinking about settling down."Do you think it's smart for Hayden to do her own thing at this point
