How I Met Your Mother's Alyson Hannigan is going to be a mother again, her rep confirms exclusively to Us Weekly.

On Thursday, the actress, 37, was photographed chatting on her cell phone in Santa Monica wearing jeans, a vest and thin red crocheted sweater -- snug enough to reveal an undeniable baby bump.

"Alyson is thrilled to be pregnant!" a source close to the star tells Us Weekly. "She's been wearing baggy clothes to cover the baby bump."  Thankfully, Hannigan won't have to crouch behind couches or wear oversize dresses to hide her belly on her hit CBS sitcom -- her HIMYM character, Lily, is also currently expecting!

The star and husband Alexis Denisof are already parents to daughter Satyana, 2.

Married since 2003, Hannigan and British actor Denisof, 45, met as stars of Buffy the Vampire Slayer and its spinoff, Angel.

"It filled a void I never knew was there -- it's the most amazing experience of my life. I just feel so blessed to get to be on this journey, to be a mommy. [Satyana] is just the greatest baby.
