No one can bring out the stars quite like Clive Davis! The music mogul’s Pre-Grammy Gala & Salute to Industry Icons (this year honoring Universal Music Group Chairman and CEO Doug Morris) is an annual tradition and one of the biggest parties of the year. And with a bevy of stars – including Jay-Z, Rihanna, Katy Perry, Russell Brand, Taylor Swift, Ne-Yo, Sheryl Crow, Adam Lambert and Barbra Streisand – in attendance, Saturday night’s bash at the Beverly Hilton Hotel was no exception.

“It’s one of those parties that you have to come to,” Ciara, in head-to-toe Givenchy, told PEOPLE on her way in. “I’m excited to see everybody! It’s cool to see people that you know, people that you don’t know. It’s always great to see Clive, and I’m just looking forward to having a great time.”

Fergie, in a Zuhair Murad party dress, breezed down the red carpet in a hurry, stopping only to have a happy chat with Nick Jonas. But the singer had a good reason to rush: The Black Eyed Peas opened the show with Slash singing the classic Guns n’ Rose’s tune “Sweet Child O’ Mine.”

Newly engaged couple Katy Perry and Russell Brand sat front-and-center with pals Rihanna and Ne-Yo. On his way in the British comedian told PEOPLE his idea of a dream wedding. “I would like to have a Victorian wedding with a bunch of chimney sweeps and ravens and people on Penny Farthings coming along,” he joked.

Later, Rihanna caught up with old flame Drake just as Harry Connick Jr. went on and got everyone clapping along to his amazing piano playing.
