The 25-year-old Vampire Diaries actress and the 22-year-old When the Game Stands Tall actor were also seen sitting together on top of a smaller commuter boat that day. They were joined by several friends while enjoying the beautiful weather.
Alexander, who is currently being featured in the JJ Spotlight Series, told us about the scare wars he has with Nina.
“Right now, she’s winning, but it’s only because I’m working on Vikings, and she came to Dublin and scared me. So I’m going to go to Atlanta and gonna get her back, so it’s still on,” Alexander exclusively told us. “She had a friend, that also works with me, and she flew out, and she was supposed to come visit but she came and visited a couple days early. I walked into the hotel lobby and she was hiding behind a wall, and she freaked me out. I was really happy to see her, but I was also very angry that she got me.”
