On Monday night at Los Angeles’ Hollywood Palladium, Macaulay Culkin joined chart-topping singer Lizzo onstage for a surprise dance-off during her call-and-response performance of “Gigolo Game”.

The Home Alone star shared a video from Monday night’s concert, writing as a caption, “When @lizzobeeating asks you to do a silly dance… You get up there and do a silly dance.” Culkin showed off his dance skills with “the sprinkler” and “the shoot,” while Lizzo’s dancers followed his lead.

The pair of entertainers may seem an odd match, but it turns out they have been friends and collaborators for many years. Lizzo toured in support of Culkin’s band, The Pizza Underground, in 2014, and Culkin appeared in the singer’s recent video for “Faded”.

“[Macaulay Culkin is] really supportive and one of the best people I’ve ever met in my life,” Lizzo told British music mag NME last year. “Not just because he’s Macaulay Culkin, but because he is an awesome human being.”
