Lance Bass has proposed to his fiancé for a second time.

The former ’N Sync star first became engaged to Michael Turchin last August.

And his partner revealed Lance had popped the question once again on Sunday when he posted a photo on Instagram of a ring with black diamonds and a gold band, US Weekly reports.

"Who gets proposed to a second time on the first anniversary of the first proposal?? This guy!!!" Michael gushed.

News of the second proposal comes shortly after the couple returned from South Africa on vacation.

Lance and Michael began dating in December 2011, five years after the singer came out as gay.

In 2013, Lance reunited with his 'N Sync bandmates for a special performance at the MTV VMAs in celebration of Justin Timberlake, the recipient of the network’s Video Vanguard Award that year.

Taking to Twitter not long after the show, he revealed the fulfillment he found in finally getting to take the stage as a proud gay man.

"For the first time ever I got to perform w ’N Sync as an out entertainer and was thinking of this man," Lance wrote, sharing a photo of himself with Michael.

Lance previously dated reality TV star Reichen Lehmkuhlin in 2006 and was later linked to Brazilian journalist and actor Pedro Andrade and hair stylist Ben Thigpen.
