"Heroes" jailbait princess Hayden Panettiere and boyfriend Stephen Colletti were caught hand-in-hand at a matinee on Monday. Then they got closer.
The twosome was spotted at The Grove cinema in L.A., where they locked lips and cuddled through a screening of "Shrek The Third." PDA at a kiddie flick -- some material may not be suitable for children!
Panettiere was wearing a solid band on her engagement ring finger -- is a commitment near for these two? Hayden can legally walk down the aisle when she turns 18 ... in August.
