President Bush's parents George and Barbara just want what's best for their WASPy descendants, particularly on the occasion of the wedding of their beloved, dignified granddaughter Jenna. That's why they don't want David Lauren, son of Ralph Lauren, to attend. See, David has been dating Jenna's cousin Lauren Bush for three whole years, and still hasn't proposed marriage. "Where's the ring, David?" one source near the family told the Daily News. Also, he's an ancient 36 and she's an innocent 22. And, no doubt worst of all for the patrician Bushes, David Lauren is a Jew, and his Jewy-ness might infect precious Lauren:

"There are religious differences," one [source] points out. "Would he expect her to convert to Judaism?"

Lauren's mother, Sharon, is a devout Christian.

The Daily News did find one Bush insider to dispute George and Barbara Bush's disapproval of Lauren, and to point out that even the elder George Bush didn't get to invite siblings.

NB to David: If you do get invited, don't bring up Grandpa Prescott. So awkward.
