Neil Patrick Harris Expecting Twins

The 'How I Met Your Mother' actor tweeted the news on Saturday.

"How I Met Your Mother" star Neil Patrick Harris is going to be a father.

On Saturday (August 14), the dad-to-be tweeted the news that he and his longtime partner David Burtka are expecting twins.

"So, get this: David and I are expecting twins this fall," Harris wrote on his Twitter page. "We're super excited/nervous/thrilled. Hoping the press can respect our privacy..." E! Online reports that the twins are due in October via a surrogate.

Harris is facing fatherhood this fall but he also recently delivered another significant project. The actor and occasional awards show host directed a production of the Pulitzer Prize-winning musical Rent, at the Hollywood Bowl in Los Angeles. Harris steered a celebrity cast, which included Vanessa Hudgens and the Pussycat Dolls' Nicole Scherzinger, through the production about a motley crew of New Yorkers navigating life in the '90s. Harris recently told MTV News that one of the reasons he's a fan of "Rent" is because of the inclusive message of the musical.

"As people get to be older and older, they start disassociating themselves from different types of people," Harris observed. "And this 'Rent' world sort of does the opposite: It encourages all of that. The diversity that these 25 people have ... just fills your heart."

In addition to welcoming two bundles of joy, the actor is up for three Emmy Awards. Harris was originally only recognized for two nominations but Emmy bosses bumped up his official nod count after inadvertently snubbing the actor for his work as the host of the 2009 Tony Awards.

Leave your well-wishes for the couple below!
