Ryan Reynolds
likes to keep it in the family! Well, sort of.

The 36-year-old posed for pictures with one good-looking lady at the premiere of his latest flick, "The Croods" ... and it wasn't his 25-year-old wife, Blake Lively!

Blake was there, but the two didn't take a single picture together. Strange, no? However, Reynolds did manage to snag some red carpet shots with Blake's sister, Robyn Lively

You may remember the oldest Lively sister from her starring roles in 1989's "Teen Witch" and "The Karate Kid, Part III."

Ryan was also joined by his costars Catherine Keener, Emma Stone and Nicolas Cage for the New York City premiere on Sunday.

Think Blake and Robyn look alike? Sound off below, and see more famous siblings in the gallery!
