Kirstie Maldonado is Square-ing up for New Years Eve…

The 23-year-old half-Mexican, part Spanish-American singer and her fellow Pentatonix members have been added to the list of performers for this year’s Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest in Times Square, New York City.

It will be Pentatonix’s first appearance on the annual holiday extravaganza.

In addition to Pentatonix, the list of recently added performers includes Nick Jonas, Macklemore & Ryan Lewis, and Joe Jonas-fronted DNCE.

Additionally, Alessia Cara, OMI and Nathan Sykes will join the fun of the New Year festivities.

In Los Angeles, there will be the West Coast celebration hosted by Fergie and will feature the last performance from One Direction before their indefinite hiatus.

Dick Clark’s New Year’s Rockin’ Eve will broadcast live at 8 p.m. EST on Thursday, December 31 on ABC.
