No female BFFs took the stage this time, but Taylor Swift's squad did gain more star power on Friday night at the first Los Angeles concert of her 1989 tour.

The "Blank Space" singer brought onstage OneRepublic's Ryan Tedder and Lakers star Kobe Bryant. She and the fellow singer-songwriter performed his band's 2013 pop hit "Counting Stars."

It was so awesome to collaborate with him on 'Welcome to New York' and 'I Know Places,' then share the stage with him," Swift wrote on Instagram, alongside a photo of the two.

Bryant, whose team's home base is Staples Center, appeared onstage as Swift performed her runway-themed hit "Style."

"The screams you hear from an LA crowd when Kobe walks out onstage are so deafening you think you may have permanent hearing loss," Swift said on Instagram. "But it was SO WORTH IT."

He also arrived bearing a gift: Bryant presented Swift with a banner that reads, "Taylor Swift, Most Sold Out Performances" for her record-setting 16 sold-out shows, the largest number for any artist at Staples Center.

Law & Order: SVU star Mariska Hargitay, whose character inspired the name of one of Swift's cats and who appeared in the singer's "Bad Blood" video, was spotted in the crowd, E! News has learned. Hargitay had met Swift and appeared onstage with her at her concert in Philadelphia in June. Many "Bad Blood" stars are close friends of the singer and have also made appearances at her shows.
