Separated at birth?

So here we were looking up Lou Diamond Phillips on IMDB (don't ask), and came upon a photo of him with a nice young lady. "Hey, it's the chick from Enterprise", I pointed out, helpfully. But her name was listed as "Yvonne Boismier Phillips". An error? A pseudonym? Then I noticed the last name. Perhaps that's his wife? Couldn't be. She would never leave me for that phoney. "Jolene Blalock!" I interject, her name springing to mind a bit too readily for my wife's liking (I blame Blackwalt). So off to IMDB again for some clarification.

Except it didn't really help at all...

That's the alleged Mrs. Phillips on the left, and our favourite Vulcan on the right.

Coincidence? Discuss.
