Harris and Burtka are using a surrogate, according to E! Online, which first reported the news. The couple has been together for six years.

The How I Met Your Mother star has plenty of reasons to celebrate this week after receiving a last-minute third Emmy nomination earlier this week for hosting the Tony Awards.

Harris is also nominated for best supporting actor in a comedy for How I Met Your Mother and best guest actor in a comedy for his appearance on Glee.
