Pregnancy Is As Easy As Pie For Alyson Hannigan

Between planning her 3-year-old daughter Satyana's bday party -- while celebrating her own on March 24! -- making the promotional rounds for her newest film, American Reunion, and being many months preg, mommy-to-be Alyson Hannigan has had quite the busy month!

The How I Met Your Mother star played-up her growing baby bump in a blue flowered maxi dress, jean jacket and a bright red scarf, while strolling with hubby Alexis Denisof and her darling daughter in Santa Monica, on Sunday afternoon.

Hannigan's American Pie castmates are currently headed to Australia to continue promoting the film, but unfortunately her baby bump has left the actress permanently grounded!
