Lambert was clearly as smitten with the performance as her fans were, because she posted a sweet message about the duet the following day. 

"London, England! Thank you so much," she wrote. "What an amazing night. And I got to sing a song with my ? @andersoneast #getawaydriver ?@blusanders #myfriendblu"

This isn't the first time the couple have shared the stage. On Valentine's Day 2016, Lambert showed up to East's show in Northampton, Massachusetts, and did not keep a low profile.

Instead, she joined the 29-year-old singer and former Voice contestant Gwen Sebastian for a fun rendition of Mariah Carey's 1995 hit, "Always Be My Baby."
