"In the studio with Nick Carter cookin up some heat! Oh yeahhhhhhhhhhhhh!!!!" - DaRealSD (Shawn Desman, who opened for the Backstreet Boys on the This Is Us tour)
"WOW! Wrote 2 great songs with @Tebey and Nick Carter today! Tomorrow is another day! sleepy time:-) #fb" - DaRealSD (Shawn Desman is a Pop/R&B singer so this indicates the sort of style that Nick is going for if it is indeed for his solo project)
By the way, Tebey is a country singer but has recently written some pop tunes and seems to be influenced by the Swedish sound as he has travelled there many times. He has co-written with Kristian Lundin.
