Michael Tran/WireImageStar power was in full effect and there was even a High School Musical mini reunion at Selena Gomez's Los Angeles concert Friday, the latest stop on her Revival tour.
Celebs spotted at the show included High School Musical alum Vanessa Hudgens, 27, her sister Stella Hudgens, 20, and her friend and former co-star Ashley Tisdale, 31, who arrived with husband Christopher French.
The two actresses were seen walking and talking together. They have hung out several times since their High School Musical days and they and other cast members reunited several months ago for an official onscreen reunion to mark the Disney Channel franchise's 10th anniversary.
Halle Berry, 49, Tobey Maguire, 41, Jason Derulo, 26, The Vampire Diaries' Arielle Kebbel, 31, Brooklyn Beckham, 17, Peyton List, 18, Bailee Madison, 16, and Girl Meets World stars Sabrina Carpenter, 17, and Rowan Blanchard, 14, also attended.
The Hudgens sisters, Tisdale and her hubby, Brooklyn and Rowan were all spotted at the VIP suite at the stadium's Hyde Lounge, at a private gathering hosted by Call It Spring.
In addition, Gomez's friend and Australian pop star Cody Simpson, 19, was seen backstage, hanging out in a room next to the "Come and Get It" and "Kill Em With Kindness" singer with several guy friends, E! News has learned exclusively.
Also spotted backstage was opening act DNCE, Joe Jonas' group. He was seen stretching before their set.
Gomez heads to Anaheim, California for another show Saturday, after which she'll perform in Canada and then take almost two weeks off before heading to Asia for more concerts.
