Say it isn’t so! The couple reportedly called off their nuptials after a vicious lovers’ spat.

Neil Patrick Harris and David Burtka announced their engagement after the Marriage Equality Act was passed in New York in 2011, but a recent alleged spat may stop them from ever walking down the aisle.

“They’re barely speaking, and as of now there’s no wedding in the immediate future,” an insider revealed to The National Enquirer.

The reported fight started when the How I Met Your Mother star, 39, got extremely angry over something David, 37, an E! Network correspondent, said. They were allegedly on their way to a big Hollywood party, when the fight erupted. It allegedly got so heated that Neil and David didn’t even go home together that night.

“They walked into the party mad at each other,” recalled the 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,” confided the insider.

Gossip columnist Rob Shuter, also known as Naughty But Nice Rob, tweeted on Feb. 27, “BREAKING: Report saying Neil Patrick Harris and his longtime partner David Burtka have called off the wedding. I haven’t confirmed yet.”

If Neil and David do split, they’ll have to fight over custody of their 2-year-old twins, Gideon and Harper. They started dating in 2004.

HollywoodLife.com reached out to Neil and David’s reps for comment.
