After getting linked to several celebrity hotties at Comic-Con, the Vampire Diaries star spent some time having a blast on a yacht in Ibiza, Spain with Alexander Ludwig.
Clad in a black bikini, the 25-year-old Vampire Diaries star was all smiles Aug. 22 as she jumped from the yacht into the ocean with a group of friends, according to E! Online. The Hunger Games star was right there with her as they took the dive, showing off his chiseled bod in blue swim trunks.
Considering Nina has been the subject of more than a few romance rumors as of late, we wouldn't be surprised if the sighting of her hanging out with Alexander sparked another one.
According to the site though, it appears (for now, at least) that the duo is just friends. Following her getaway to Ibiza, Nina jetsetted back to the states, where she hit the stage with Trey Songz looking gorge in a body-hugging red and black dress to present the award for best rock video. Then, the duo sparked even more romance rumors.
While they were on stage, the "Na Na" singer made sure to cozy up to the brunette beauty, stepping behind her and saying "I can always get behind a lady."
We wouldn't be surprised if he became her seventh "possible boyfriend" of the summer.
