Hayes MacArthur and Ali Larter: Engaged!

Hayes MacArthur will be seeing Ali Larter naked for the rest of his life.

The actor and Heroes actress are engaged.

"It's true," said a rep for the actress. "They're thrilled."

Hayes MacArthur and Ali Larter will be one another's Heroes for life.

No wedding date has been set and this will be the first marriage for both. For Larter, the proposal was anything but a surprise; she's been more than ready to marry MacArthur, who has appeared on How I Met Your Mother, almost since she met him.

"I told my boyfriend after three weeks that I wanted to marry him and that we could do it tomorrow," Larter recently said. "I look forward to that time when I'm home with babies."
