They're attached at the hip!

Ben Affleck and Lindsay Shookus got back to work this afternoon after their hot date in Hollywood last night, and we don't remember the last time we saw one of them without the other. The Oscar winner never even spent this much time with Jennifer Garner when they were married!

We can't wait to see how this relationship plays out, because it's not exactly the easiest of situations. The SNL producer's work and young daughter are based in NYC, while the actor's three children live and go to school in LA. That makes it virtually impossible for the lovebirds to live under the same roof!

Given the fact they've secretly been together for over three years and they're obviously serious, they've got a few things to figure out if it's going to work in the long term.

A source tells X17:
    "Ben and Lindsay both ended their respective marriages for each other. This is more than just a fling, and they see themselves being together forever. That said, they're really stressed trying to make the big decisions about their future. Flying back and forth between coasts is working for now, but they both know it's not a permanent solution. Ben's inner circle thinks Lindsay is going to drop everything to be with him."

We hope they're happy, because they've risked a lot for this romance!
