Justin Bieber wants you to know ... he's on vacation.
The 18-year-old singer posted shirtless photos of himself on Instagram Dec. 30, simply writing, "Vacay."
Bieber and his on-again-off-again love Selena Gomez are reportedly in Puerto Vallarta, Mexico -- where a fan spotted them arriving today.
"Time for a little relaxation," Bieber tweeted Dec. 29, after announcing the upcoming release of the acoustic version of his chart-topping album, "Believe."
"8 wasnt enough. had to write some more new ones. now im putting out 10 SONGS on #BELIEVEacoustic . Im telling u. PREORDER it now :)," he wrote, later adding, "Won't let you down."
