Some very exciting baby news for this TV star!

As avid How I Met Your Mother fans, we've come to think of the characters as our best pals.

So we're over the moon with the news that actress Cobie Smulders, who played Robin Scherbatsky on the show, is pregnant with baby number two. 

Of course, we'd prefer it if she was having a baby with Ted Mosby, but you can't have everything!

Cobie wed her husband, Saturday Night Live comedian Taran Killam, in 2012. The couple have one daughter together, five-year-old Shaelyn Cado.

A source close to the pair said they had been planning on having more children once Cobie's work commitments eased off. "They talked about growing their family once she was done with How I Met Your Mother and moved to New York," said the friend. 

Becoming a mother for the second time will no doubt be an easier adjustment, as Cobie no longer has the pressures of a full-time filming schedule since HIMYM ended earlier this year.

Speaking not long after Shaelyn's birth, Cobie said she was happy but tired. "I think I sleep an average of four hours a night now, so it's just like functioning on fumes sometimes. But it's the best." We're not sure we would have been quite so positive!

The actress said she was lucky to be in a position to have help handling her busy schedule. "It’s a lot of work and I feel extremely grateful because my job allows me a lot of flexibility and freedom… And financially I am able to have a lot of help around."

Congratulations to the growing family!
