The pair have already started planning their baby shower, according to E! News, who first reported the twins were on the way, via a surrogate.
“So, get this: David and I are expecting twins this fall. We’re super excited/nervous/thrilled. Hoping the press can respect our privacy,” Harris “tweeted.”
Later in the day, the expectant dads hammed it up at Disneyland.
Harris is up for three Emmys this month — one for Best Supporting Actor Comedy on CBS’ “How I Met Your Mother,” a second for Guest Actor in a Comedy Series for “Glee” and a third for hosting last year’s Tony Awards.
Burtka has experience with twins; he helped to raise twins from a relationship with a previous boyfriend, although he wasn’t a primary parent to them.
