Nick Shacks Up With Vanessa

Things are getting ever more serious between Nick Lachey and his summer squeeze Vanessa Minnillo, just as reports of a relationship between his ex Jessica Simpson and singer-songwriter John Mayer heat up.

A TMZ spy who recently rode in an elevator with the pair at Minnillo's apartment building say they were "totally into each other," very affectionate with one another, and were oblivious to anyone around them, and Lachey has been spotted shacking up chez Minnillo regularly when he's in Manhattan.

A source in this morning's Page Six says that Lachey was "still pretty obsessed" with Jessica until very recently -- a week ago, to be precise -- though he's "over" their relationship now. This should all make for an interesting scene at tomorrow's VMAs when Simpson, Lachey, and Minnillo will all be in attendance together. And just yesterday, reports emerged of the burgeoning romance between Jessica and Mayer, which would be Jessica's first true romance since after the ex-"Newlyweds" break-up.

Meanwhile, Lachey has become a (very) minor sports mogul as he'll be one of several owners of a new American Basketball Association basketball team in LA, called "The Hollywood Fame," which he will own with Stacy Keibler and Jamie Lynn Sigler's ex-hubby AJ DiScala, among others. reports People.

"It's an exciting time in their life," says a People source. It was not immediately clear whether Leinart and Cameron would be raising the child together, or if, indeed, the pair were still together. TMZ has spotted Leinart, who has already begun play as a back-up quarterback for the Arizona Cardinals, cavorting with Paris, as recently as May.

Saturday night at LA club Republic, Lindsay kept things very low-key as she hung out with Morton -- who's a teetotaler -- and her new chum, celebrity DJ Samantha Ronson, who also doesn't drink. And though Lindsay had originally planned to get to New York this week, Morton convinced her otherwise, and she called friends and said, "I don't need to be there." What's more, Morton has brought another good influence into Lohan's life -- a new dog.
