Lizzo stepped in last minute for the end-of-the-year holiday performance after the Yeah Yeah Yeahs announced they’d have to stand down because guitarist Nick Zinner is recovering from pneumonia. The night was hosted by Austin Butler and was cast member’s Cecily Strong’s final show with the SNL.

She performed her song “Break Up Twice” for her set, wearing a white slip and sitting on a bed in reference to the famous painting “Blue Monday” by artist Annie Lee.

Later, she performed something festive for the holiday, singing “Some Day at Christmas.”

The musical artist has been dating her boyfriend Myke Wright for some time, though she has always been fairly private about her love life. This past Tuesday on The Howard Stern Show, she discussed being in a dedicated relationship, saying, “We’re not playing any games with each other anymore. We’re very much locked in.”

Though she and Wright have known each other for years, she wasn’t ready for a relationship at first.

“I had a lot of sh-t to do, and I still was very much in my ‘I feel un-loveable’ place, and I still was very much not where I wanted to be career-wise,” she added. “Even if a person came around that I was googly-gaga about, I had these wild defenses up that made it almost impossible for a true, intimate relationship to occur.”
