Carrie Underwood and Mike Fisher don't have a name for their unborn son just yet, but the country star and NHL player aren't the first celebs to hold out on a reveal.

Carrie Underwood Gets Some Very 'Honest' Motherhood Advice 

Underwood has insisted that she and her husband have tossed around a few contenders, but might just have to meet the little guy before deciding who he is. The fact that they haven't been able to find a name they both like has also seemed to be an issue, with Fisher coming up with more joke names than actual ones.

Even if Underwood and Fisher do agree on a name, it's possible they will keep things quiet for the time being. They are already keeping the baby's due date a secret and in terms of wanting a little privacy, they aren't alone.

Carrie Underwood's Husband 'Can't Wait' To Meet Their Son 

Plenty of celebrities have waited days or even months to reveal the names of their children to the public. In 2010 Isla Fisher (Now You See Me) and Sacha Baron Cohen (Borat) decided to keep their second daughter's name under wraps for six months before announcing that it was Elula Lottie Miriam.

True Blood stars Anna Paquin and Stephen Moyer welcomed their twins in 2012, though the couple waited a year before confirming that they'd gone with Charlie for their boy and Poppy for their girl.

Other in the business to follow suit include Ryan Gosling, Natalie Portman, and the famously private Adele.

So when will the public get to find out little Fisher's moniker? Will he actually be named "Fly" as some of the joking has suggested?

Underwood is expected to give birth to her baby boy this spring. Fans will just have to wait until then.
