Stern commented, saying, "You guys break up and you say, 'Look, I don't want to have a baby with you. I'm not involved with you anymore.'"
Vergara responded, asking, "Can you blame me?"
Stern replied, "I can't blame you."
Now her ex-fiance, Nick Loeb, says he will appear on the Today show.

Matt Lauer made the announcement on Tuesday, "We'll hear more of Nick Loeb's side of the story. He'll join us for an exclusive live interview this coming Thursday."
Vergara's Howard Stern appearance is making national news.
She added, "I totally understand him, but the thing is this - that fortunately and unfortunately there is law. You signed papers, legal papers, and if it was so serious for him, this issue, which I totally respect if it's serious for someone, then you should have taken it more serious at the time like I did."
Vergara says she doesn't want to have a child with someone she's not in a relationship with.
On Stern's show she added, "It needs a loving relationship of parents, you know, that get along that don't hate each other."
Robin Quivers asked, "You hate each other now?"
Vergara responded, "Well, I don't hate him. But, obviously he has a problem with me."
Stern replied, "Yes, well, when you break up with a guy there's a problem."
