Taylor Swift -- Kobe Bryant Jumps Onstage in Banner Night (VIDEO)

Taylor Swift had them hanging from the rafters at the Staples Center in L.A. Friday night, and something else was hanging from the rafters ... with a little help from Kobe Bryant.

Taylor opened the first of 5 concerts at Staples, and Kobe jumped onstage to welcome her to his arena ... and he came bearing gifts.

Who's the bigger celeb ... Kobe or Taylor? Up for debate.
