UPDATE: Sounds like this rumor was way off! 

Neil Patrick Harris has taken to Twitter to refute the rumors that he and David Burtka had called off their wedding following an argument at a party.

The rumor "is cray cray," Neil writes. He explains that they've "never had a wedding date," but that they're "on a cruise as I write. He's rad. All good."

Phew! We love these two together, so we are relieved that they sound happier than ever! And we can't wait to see them someday "suit up" for their wedding!

Original story: Here's some news that is definitely not legendary.

Rumor has it that Neil Patrick Harris and longtime boyfriend David Burtka have called off their wedding, according to Hollywood Life.

“They’re barely speaking, and as of now there’s no wedding in the immediate future,” says a source. 

Apparently, the 39-year-old How I Met Your Mother star got upset about something that David said as they were on their way to a recent Hollywood party. Things got so tense that the couple reportedly did not even go home together.

“They walked into the party mad at each other,” says an insider. “They both threw back a couple of whiskeys, and that only made things worse.”

“Neil’s still mad, and David is terrified he’s going to lose him,” the source continues.

Neil and David have been together for quite some time, as their first public appearance as a couple was at the 2007 Emmy awards. They are parents to two-year-old twins Gideon and Harper.

If this rumor is true, it would mark the third high-profile split announcement this week, following those of Michelle Williams and Jason Segel, plus Rachel McAdams and Michael Sheen. We're sobbing over here!

Gossip columnist Rob Shuter acknowledged the Neil-David rumors on Twitter on February 27 but pointed out that they have yet to be confirmed.  

“BREAKING: Report saying Neil Patrick Harris and his longtime partner David Burtka have called off the wedding," Rob wrote. "I haven’t confirmed yet.”

As of now, we're just going to hope that these rumors aren't true, since Neil and David have been so cute together for so long. Don't do this to us, you two!
