Vegas Golden Knights star William Karlsson is one step closer to becoming a married man.

Karlsson and his fiancée, former "Bachelor" contestant Emily Ferguson, picked up a marriage license Saturday at the Marriage License Bureau in Las Vegas.

Ferguson shared a video on Instagram of her and Karlsson arriving at the office, complete with an Elvis impersonator and Chance the Golden Knights mascot celebrating the occasion.

They also received a specialty version of the marriage certificate keepsake featuring cartoon versions of Karlsson in a suit of armor and Ferguson in a wedding dress.

"Thank you @vegasweddingcapital for this very memorable moment getting our marriage license today!" a caption on Ferguson's post reads.

There's been no word yet on when the couple will officially tie the knot.

Ferguson's twin sister, Haley, celebrated her wedding to hockey player Oula Palve at Resorts World Las Vegas earlier this month.
