Neil Patrick Harris and his longtime partner David Burtka will have their hands full later this year. The actor confirmed the pair are expecting twins.

"So, get this: David and I are expecting twins this fall. We're super excited/nervous/thrilled. Hoping the press can respect our privacy…" he wrote on Twitter.

According to E! Online, which was first to report the news, the couple are going to become parents with the help of a surrogate.

They've been together for about six years.
