Remember after Kelly Rutherford welcomed daughter Helena on Monday, and we expressed hope that she and her estranged ex, Daniel Giersch, could settle their differences amicably, for the good of their children if nothing else?

Doesn't look like that's gonna happen.

According to sources, Giersch learned of Helena's birth yesterday the same way we did - from celebrity gossip reports online. And he's far from pleased.

An insider says the birth came as a surprise to businessman Giersch, 36, who is currently in midst of a heated divorce with the Gossip Girl actress, 40.

Giersch had previously filed legal paperwork to be notified when Rutherford goes into labor, says the source. But apparently this did not take place.

Kelly Rutherford, Hermes and Daniel Giersch in happier times.

The source tells the tabloids that "[Rutherford] failed to tell him and instead he found out this morning on the Internet. He was robbed of an opportunity to be at the hospital when his child is born. He is sad and disappointed."

After two years of marriage, Kelly Rutherford filed for divorce from Giersch in January - about a month after announcing she was pregnant with baby #2.

The two have since engaged in a brutal war of words over who is the better parent as they continue to fight for custody of their little son, Hermes, 2.

Again, maybe they'll find a way to stop the madness. We'll keep you updated, even though we wish there were nothing to report along these lines.
