The Undertaker may portray a dead man on WWE television, but his relationship with his wife Michelle McCool is alive and well.

The former WWE Diva took to Instagram on Sunday and posted a photo of her and the "Demon from Death Valley" as they celebrated six years of marriage together. The happy couple tied the knot on June 26, 2010, in Houston, Texas.

The Undertaker hasn't been seen in the WWE since his Hell in a Cell match with Shane McMahon at WrestleMania 32 back in April. It was a fairly confusing storyline because the creative team -- which was dealing with an injury-riddled roster -- never fully explained why 'Taker was doing Vince McMahon's bidding.

It also never really made any sense because the stipulation was if The Undertaker won, Shane-O Mac wouldn't be able to have control of "RAW." 'Taker did end up winning the match, but he has disappeared from the WWE, while Shane McMahon has controlled the flagship show alongside his sister Stephanie McMahon.

Shane will also be in charge of either "RAW" or "SmackDown" when the brands split on July 19 with the first live edition of "SmackDown."

The latest storyline developments have rendered the entire WrestleMania angle pointless, and now the world awaits a return for The Undertaker. The WWE legend has had retirement rumors creep up after his bout with Shane, but Jim Ross has vowed that he doesn't believe 'Taker is hanging up his boots.

"Don't you think that if The Undertaker had retired from WWE that [we] would have all known about it?" Ross wrote in a Q&A at JrsBarbq.com last month. "Taker is not retired."

These types of rumors surround The Undertaker every year, most notably when he lost The Streak to Brock Lesnar at WrestleMania XXX in 2014.

The Undertaker actually took on a busier schedule last year, facing Lesnar at SummerSlam and Hell in a Cell then battling The Wyatt Family at Survivor Series.

What happens next is anyone's guess, but at least The Undertaker appears very happy alongside McCool:
