Actor Neil Patrick Harris has denied a rumor that his relationship with David Burtka is on the rocks.

Harris, the star of CBS' How I Met Your Mother, and celebrity chef Burtka entered a California domestic partnership in 2004. The couple welcomed twins Gideon Scott and Harper Grace, who were born via a surrogate, on October 12, 2010.

The celebrity website CelebDirtyLaundry.com suggested that Harris had an affair with dancer Sonny Fredie Pedersen. Harris and Pedersen performed together at the 2010 Oscars, which Harris hosted.

“Apparently, Harris paid the dancer to keep quiet and never expected that anyone would find out about it,” the website wrote. “He's [Burtka] devastated – ever since Harris and Burtka had their babies, they have been living in a love bubble and Harris fears that this could end their relationship.”

“Just saw this,” Harris, 37, tweeted with a link to the story to his more than 1 million followers. “Total bunk, absolute nonsense. Annoying. Thanks for needlessly worrying David. 'Preciate that.”

Harris just wrapped up a three-day run of Stephen Sondheim's Company with Broadway diva Patti LuPone and Stephen Colbert.
