Alyson Hannigan 'I Feel Like A Stoned Koala Bear'

Alyson Hannigan is finding that being pregnant not only gives her cravings – but makes her feel like a stoned Koala bear.

"I get tired a lot and I have pregnancy brain, which I never realized was a thing but it is," the expectant mom said on The Ellen DeGeneres Show Friday.

"I sort of feel like a Koala bear where I'm slightly stoned all the time and I'll say the wrong word."

Quipped Ellen DeGeneres, "I'm not pregnant, but I have that brain too. I don't have an excuse."

As for the baby's gender, Hannigan, 34, says she and her husband, actor Alexis Denisof, have found out their child's sex, but prefer to keep it private until its birth. "We're just not announcing to the world," said the How I Met Your Mother actress. "It seems a little personal."
