The former `Ugly Betty` actress - who already has a 23-month-old daughter, Paloma Louise, with husband Noah Lebenzon - is expecting a boy but admits the couple are struggling with names because they want something that pays tribute to their Spanish roots yet is still easy to pronounce.
She told Latina magazine: "We know it`s a boy! We are trying to come up with some names that we can agree on.
"It has to be Spanish, but something non-speakers can pronounce without mauling. Suggestions? I`m open."
Ana welcomed her first child into the world on June 27 2009 and she was "elated" at becoming a mother.
A spokesperson for the star said: "She is elated and completely glowing. She is surrounded by her friends and family and so happy to be a mom.
"She is just really enjoying the moment. The baby is absolutely beautiful."
During her pregnancy, Ana, 40, said she was "really enjoying" the experience of carrying her first child.
She said: "I`ve heard lots of horror stories, but I`m actually really, really enjoying this."
