"This may be the end of my @americanidol journey, but best believe it’s only the beginning!" Trevor posted . "I made so many amazing friends on the show and won over so many incredible fans that I know will stay with [me] on my journey. In fact. I’ll be releasing my first song in a few days!!!" (That single is called "Walls" .) Trevor also went on to attend the American Idol finale . He marked the occasion by posting a photo of himself with an Alpaca. It's unclear whether or not these events were related, but hey, look at that cute lil' fuzzy animal.
