Pacey and Dawson, together again!

We got some major WB flashbacks last night, as "Dawson's Creek" stars Joshua Jackson and James Van Der Beek unexpectedly met up for one amazing photo-op.

"The most pleasant run-ins can happen in the most unexpected places," James captioned the pic above on his Instagram page, showing him arm-in-arm with his former on-screen BFF.

"It's so funny, it just seems like something so far away, it seems like another lifetime in my experience," Van Der Beek recently told Huffington Post about his time on the show.

Former costar Katie Holmes also opened up about working on the "Creek" just last week.

"You know, we all still keep in touch and support each other, and luckily, we all have been able to stay busy," she said. "We had a really wonderful time. It was six years of our lives, and we were all really passionate about making it the best it could be. We really believed in ourselves. I love them all so dearly. I'm so excited for everyone and proud. I can't believe… it seems like yesterday, and then it seems like a hundred years ago when we made it. We really did have a good time."

The series lasted for six seasons from 1998 to 2003.
