Entertainer Beyonce performs on stage during "The Mrs. Carter Show World
Tour" at the Staples Center on July 1, 2013 in Los Angeles, California.
L.A.'s Staples Center was the place to be on Monday, July 1, when
Beyonce took the stage for the third show on the U.S. leg of
her Pepsi-sponsored Mrs. Carter World Tour. Celebs packed the house to
watch
Jay-Z's wife work the sold-out crowd of tens of thousands
of fans, giving the already super-powered event an extra dash of Hollywood glitz
and glamour.

As
Us Weekly previously reported, recently single
Robert Pattinson was in attendance at the show, wearing a
backwards baseball cap, jeans, boots, and a vintage MTV varsity jacket. But he
wasn't the only A-lister in the arena -- far from it, in fact.
Glee's
Kevin McHale was also in the crowd, along with
pregnant costar
Heather Morris, who was a backup dancer for
Beyonce before she landed the role of Brittany on the FOX series. (Morris
performed the iconic "Single Ladies" dance alongside
Chris
Colfer's character in one of the very first episodes of season
one.)

"Heather looks super pregnant -- she was wearing a long, tight dress and
holding her belly," an onlooker told
Us of the mom-to-be. "She
looked really happy though!"
Dell's VIP area in the HYDE Lounge, meanwhile, played host to Morris' costars
Lea Michele, Chris Colfer, and
Naya Rivera,
who brought boyfriend
Big Sean. A source tells
Us
Weekly that Rivera and Big Sean were kissing and dancing throughout the
night, to tunes including "Run the World," "Halo," and "Single Ladies."

Derek Hough challenged another
guest to a dance-off.

her amazing view of the stage on Instagram. Australian pop star
