Taylor Swift, 25, kicked off her five-show stint at Los Angeles's Staples Center on Friday with her typical bravado, spectacle, and a couple of special guests! Joining the star on her 1989 World Tour were Ryan Tedder, 36, of One Republic, who sang a duet of his hit Counting Stars. Also, basketball star Kobe Bryant, 36, stopped by to do a cute bit on stage with Taylor before presenting her with a banner for 'Most Sold Out Performances at Staples Center.' After the gig, Taylor tweeted: "It was a beautiful night in Los Angeles. Thank you @kobebryant, Ryan Tedder @OneRepublic, @STAPLESCenter & the fans!"
