The actress married Klaxons rocker James Righton in May 2013, and she was reminded of the fact by E! News while on the red carpet at the Tribeca International Film Festival premiere of Begin Again, costarring Adam Levine.
"Oh yeah, is it?!" she said upon being reminded.
The reporter then asked Knightley how her first year of marriage went.
"Well, we're still together so it must've been all right!" she said.
