When it rains, it pours! This past weekend Hollywood’s heavyweights poured into Hollyscoop’s certified hot spot XS nightclub in Las Vegas.

Pop sensation Beyonce Knowles made it out to a jam-packed club just moments after her killer performance at the Wynn hotel and Casino.

Beyonce Knowles may be singing about “Single Ladies,” but this married pop diva held her own court with a special VIP section.

Which she reserved for friends, family and members of her team. Joining Beyonce behind the heavily secured velvet ropes were fellow music stars Usher, Missy Elliott, and rapper Flavor Flav.

The “Sexiest Man Alive” was also in the house as Hugh Jackman hit XS along with NBA star Shaquille O’Neal, Jerry Bruckheimer, Brett Ratner.

And Academy Award-winning actor Cuba Gooding Jr.  Later in the evening, music star Ne-Yo was spotted with his entourage taking over the pristine dance-floor table.

As partygoers spotted the R & B star, Ne-Yo greeted fans and took time to pose for photos. In the meantime socialite Nicky Hilton tried to lay low as she was spotted with her man David Katzenberg and "Beacher's Madhouse" creator Jeff Beacher.
