AnnaLynne McCord, treating her sisters Angel and Rachel to a spa day at Thibiant Beverly Hills. But the outing wasn’t without a little bit of drama: There was a bit of sibling rivalry between the 90210 star’s sisters since one joined the group late and missed out on a facial. But it was all in good fun and the trio giggled and had a great time in between their treatments.

• Also in the mood for some pampering: Usher! The R&B star got a manicure and pedicure at the Amp Salon in Las Vegas’s Palms Resort & Casino. The singer, who was accompanied only by a bodyguard, opted for clear polish.

• He’s a kidder! John Mayer and pal Rob Dyrdek, playing a prank while out for the night at Hollywood hot spot MyHouse. The men, who sported velvet tuxedos emblazoned with their initials, were joined by two lovely, middle-aged women for the evening – and they initially told everybody that their dates were their mothers. Not so, a source tells us! “It was yet another prank,” the source says. “They were telling everyone it was their cougar dates and made a joke about [it] being their moms.” At least the foursome had fun as they ate caviar and partied all night!

Jaime Pressly, dropping by Fred Segal in West Hollywood with her new fiancé Simran Singh and 2-year-old son Dezi. The actress picked up a pair of red Post’age skinny jeans and also chatted with a store stylist, though she spent most of the afternoon carrying and playing with Dezi. “She was super-protective,” says a source. “They played around in the kids’ section for a while with some stuffed animals.”

The Real Housewives of New Jersey‘s Danielle Staub, partying at Ashes cigar club and steakhouse in Red Bank, N.J. The reality star danced with girlfriends in between shots of Jägermeister.
