Is this the next celeb couple? Or will everyone suspect Justin Timberlake of dating all of his co-stars now that he's single (a la Mila Kunis in Friends With Benefits)?

Timberlake and Amanda Seyfried are looking hot (see the sexy screen grab) in the just-released first trailer for In Time -- their action flick about a future where currency is not money, but time.

The two are at Comic-Con this week promoting the flick.

Rounding out the super-hot cast are Olivia Wilde, Alex Pettyfer, Matt Bomer and ... this might surprise you ... a reality star! See who it is after the jump ...
