Taylor Swift added Frozen star Idina Menzel to the long list of celebrities that she has brought onstage during her 1989 tour that has covered all of the musical hot spots, this time on Halloween. 1989 has been a wildly successful album for the Grammy-award singing talent and has produced several hit singles. 

SPIN reported that last night's (Oct. 31) performance took place at the Raymond James Stadium in Tampa, Florida and that Swift dressed up like a character from Frozen in homage to Halloween. She was wearing a costume of Olaf the snowman from the Disney film and performed alongside Menzel for the hit song, "Let It Go," for the audience.

During their performance the two singers tore off their costumes. Menzel was dressed as her character from Frozen, Elsa, for the performance. Underneath, Swift was dressed in a sparkling white mini-dress and Menzel had on skin-tight black pants and a bustier.

She also brought rising talent Alessia Cara onstage with her the night before (Oct. 30) who posted a photograph to Instagram soon after that was captioned with, "@taylorswift thank you for showing me what 55,000 people looks like. you are the classiest, sweetest, most lovely person and I can't thank you enough for what just happened. Also I can't feel my body. goodnight everyone I quit life."

In further Swift news, the singer is being sued for $42 million dollars by R&B singer and church leader Jesse Graham for a reportedly ripping off his 2013 song "Haters Gone Hate" for her 1989 single "Shake It Off." The 50-year-old artist had initially accused Swift of copying him when he saw a performance of "Shake It Off" on the Ellen Degeneres Show shorty after it's release.

He contacted representatives at both Sony Music and Big Machine Records multiple times to be credited as a lyricist on the track, along with a request for a personal selfie with the singer.
