Well, now her wikipedia entry says.Blalock legally changed her name to Jolene Ava King Rapino before the birth of her son. Blalock and Rapino gave birth to a baby boy, Ryder James Rapino on May 25 2010.
But no source is given. And the fishy thing is that her imdb.com bio is written by someone calling himself "Ryder James".
I'm not sure the date May 25th is plausible. She appeared on a number of promo interviews for her guest spot on Legend of the Seeker in January (including this one on the 22nd). Does she look pregnant there? I met my pregnant sister (who otherwise lives in Germany) around that time and it showed. My sis gave birth on May 29th.
So I guess we're still in the realm of maybe/maybe not.
But, I did look at that clip...her face looks a little fuller to me, she seems to be "glowing", and the gathers in her dress could easily hide a little weight gain, which may not be much as she'd only be in about her fourth month going on fifth here.
