That was a horrible pun, I know. I had a little trouble coming up with a headline today.

Anyway, The NY Daily News reports that Vanessa Minnillo and Nick Lachey got into a tiff when a Jessica Simpson look-alike tried to slip her number to Lachey Wednesday night at Plumm. Minnillo started yelling, "We have to talk!" before leaving the club in a huff, says our spywitness. Lachey followed, opening the door of a cab for his miffed gal pal, who ignored him and hopped into another. Meanwhile, the real Jessica dined with her mom at Border Grill inside the Mandalay Bay Hotel and Casino in Las Vegas.
