Michael Phelps Vacation Photos

Michael Phelps really meant it when he decided to go on a guys only vacation to the Maldives ... and TMZ has the bro-tastic pics to prove it.

As TMZ first reported, Phelps opted to skip traveling with his super hot new girlfriend, Megan Rossee, and instead traveled to the notoriously expensive island destination with his best boys.

Our source described the trip as "a relaxing bro getaway" that featured a lot of lounging, boating and (of course) drinking.
