Here's to hoping it's nothing too serious, but 90210 star Tristan Wilds will miss a handful of upcoming episodes due to an unidentified illness.

E! News broke the story: Wilds will be written out of the final few installments of this season, with his character of Dixon heading off on tour, as the 22-year old actor battles this disease. Details are scarce and the star's reps are yet to comment.

We'll update this scoop when more information becomes available.
