‘Glee’ Reunion: Chris Colfer Joins Darren Criss Onstage to Perform ‘Baby It’s Cold Outside’ During London Concert

Darren Criss surprised the audience at his one-night concert at London’s Royal Albert Hall by bringing Chris Colfer onstage for a “Glee” reunion. They performed “Baby It’s Cold Outside”, recalling the duet their characters sang on the series.

The song first featured in a 2010 episode, when Kurt Hummel and Blaine Anderson were fan favourites who later married in the show’s final season. The reunion comes amid renewed interest in “Glee”: creator Ryan Murphy said last month that he, Brad Falchuk and Ian Brennan had finished a reboot script and spoken with about 10 original cast members, though nobody had read it yet.
