On EARLY SUUNDAY morning one of Lee Brice's buddies, Jon Stone from the band American Young, tweeted out this pic...

These photos were tweeted on Sunday & early Monday...

That sure looks like Lee's bride-to-be, Sarah Reevely. The two have been engaged since January 2012 and have a 3-year-old son together, Takoda.

We haven't received confirmation of the nuptials from Lee...as his twitter account has been quite since Friday.

So what do you think? Did Lee & Sarah tie the knot?
