The former 'NSYNC boy-bander proposed to fiancé Michael Turchin again on Sunday, a year after the couple first got engaged.
Bass, 35, gave Turchin a beautiful gold and black ring in honor of the happy occasion.
"Who gets proposed to a second time on the first anniversary of the first proposal?? This guy!!!" Turchin captioned an Instagram of the sparkler.
Now a LGBT rights activist and host of his own SiriusXM radio show, Bass told PEOPLE in June that he and Turchin weren't rushing down the aisle.
"I literally called Michael last night and said, 'Babe, we have to plan something. I'm tired of telling everyone we haven't done anything yet!' " he said.
A source tells PEOPLE the couple now plans to marry in early 2015.
