Alyson Hannigan has mocked Gwen Stefani for calling her son Zuma.

The 'How I Met Your Mother' actress — who said she is expecting her first child with husband Alexis Denisof — insists she has no intention of giving her firstborn an unusual name as Stefani did.

When asked what she is planning to call her baby, Alyson said: "I don't know yet, but definitely not Zuma! That is taken!"

Hannigan, 34, said she is finding it difficult to contain her excitement ahead of the birth next spring.

She told Usmagazine.com: "I'm not very patient, and it's hard to wait! I'm excited, very excited!"

The redheaded beauty is enjoying being famous and pregnant, because companies have already started sending her gifts to help prepare her for her impending arrival.

Hannigan said: "I've been very fortunate because people are already sending things so they're doing the job for me! Pea in the Pod sent me my first maternity top, but, right now, I'm just wearing an empire waist — anything to disguise the little tummy!"
