Alyson Hannigan has mocked Gwen Stefani for calling her son Zuma. The former "Buffy the Vampire Slayer" actress - who recently revealed she is expecting her first child with husband Alexis Denisof - insists she has no intention of giving her firstborn an unusual name like Gwen.

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

Alyson Hannigan and her husband Alexis Denisof are expecting their first child together.

The couple - who met while starring in "Buffy the Vampire Slayer" from 1999 to 2000, where Alyson played Buffy's friend Willow Rosenberg and Alexis starred as Wesley Wyndam-Price - will welcome their first baby into the world this spring, Alyson's representative Megan Moss has confirmed.
