Las Vegas, April 30 – The Hard Rock Hotel & Casino celebrated its tenth anniversary this weekend with all kinds of events. Nicky Hilton powwowed with her sister’s new partner in reality, Kimberly Stewart, plus Kimberly’s fiancé, rocker Cisco Adler. They joined Jessica Alba, Danny Masterson and Bijou Phillips, Lance Bass, Wilmer Valderrama and Kenny G(!) for a Bon Jovi concert on Saturday. Carmen Electra and Dave Navarro, David Spade and Joey Fatone all poked around the E Hollywood Hold ‘Em Celebrity Pro Poker tournament.

Like any woman of a certain age, the Hard Rock is going for a facelift, but she wants to get bigger. A lot bigger. Mr. Hard, Peter Morton, unveiled plans for a major expansion that apparently includes Britney Spears. No, she’s not planning a Celine Dion-style gig; rather, Bit Bit and family have reportedly purchased one of the 32 bungalows planned for the complex. Each comes complete with private underground garage and swimming pool for just over $2 million. The Hard Rockers also boasted that they’ve sold all of the 1,140 condos going up in a nearby tower in six weeks. Don’t expect the Federlines and their neighbors to move in before late 2007.
