Justin Timberlake -- Hangs with Friends in Low Places ... But Not at Lance Bass' Wedding

TMZ TV

Justin Timberlake singing 'Friends in Low Places' in Nashville is awesome!  Justin Timberlake belting it out WITH Garth Brooks is even AWESOMER!!!  

And NOT so awesome -- would be Justin bailing on his ‘N SYNC bandmate Lance Bass’ wedding. Frowny face.
