File this under couples we didn't see coming. Rogue One's Diego Luna and British model and actress Suki Waterhouse appear to be dating.

The couple was spotted spending a few days together in Tulum, Mexico, and from the look of the photos, they couldn't keep their PDA at bay [1]. In the snaps posted by TMZ, the 37-year-old Mexican actor and 25-year-old British beauty look relaxed as they take a walk hand in hand, stopping only to kiss, and with Diego even grabbing Suki's behind.

If you are confused about this pairing — perhaps you had hopes he was reuniting with his ex-wife, Camila Sodi [2], since they hit the Rogue One red carpet together — Diego and Suki might have been secretly dating for over a year. They were spotted making out in Los Angeles [3] back in May 2015 and in London in August [4].
