It was a sea of stars outside Adele's show at the Greek Theatre in Los Angeles Monday evening and a paparazzi's dream.
America Ferrara and her new husband Ryan Piers Williams were snapped exiting the show as well as Kate Walsh, Christina Aguilera, Minnie Driver and a slew of others.
Aguilera couldn't contain her excitement to hang with Adele backstage, tweeting photos and her admiration for the British songstress. And Aguilera wasn't alone with tweets of love toward Adele.
"Glee" stars Dianna Agron and Kevin McHale attended (and tweeted about) the show with co-star Amber Riley who had no shame calling out her 'girl crush' on the British songstress sharing, "Dear Adele, you are officially my 'girl crush' A-freakin-mazing! Who sings like that!!!!!! Love, Amber in Shock and Awe!"
It's no secret that Riley is a fan. She posted a video of herself covering "Someone Like You" on YouTube last spring and "Glee" used not one, but two songs off "21" during the second season.
Actor Zachary Quinto called Adele "perfection" via Twitter, while Jessica Simpson used those 140 characters to do a little damage control, saying, "There are rumors that I was 'drunk swaying' at the Adele concert last night. That wasn't drunk swaying, that was professional dancing!"
Adele's tour is back on track after she had to cancel the remaining dates of her North American tour because of a bout with laryngitis. She rescheduled the canceled dates and began touring again August 9.
