Michael Sam and Vito Cammisano are reportedly engaged to marry.

The couple has yet to make an announcement, but according to TMZ.com, the proof is on Twitter.

When a college friend of Cammisano's tweeted about the engagement, Sam liked the post.

“People, he is officially off the market!!!!! My beautiful @vitcamm is getting married!!!!!!! (AHHHHHHHHH!) I love you so much Vit. So damn excited...so ready to celebrate! @mikeysam52 #vitoisengaged,” the tweet read.
