Trainor and Legend's first performance together of "Like I'm Gonna Lose You" was at the 2015 Billboard Music Awards on May 17, 2015. According to Hugh McIntyre of "Forbes", the rendition was widely applauded. It was the third most-tagged performance of the night on Shazam. William Gruger of "Billboard" wrote, "It's notable that Shazam was so popular with the slow, ballad-oriented tracks, which suggested that they were some of the most engaging moments of the evening". The performance spurred a 45% increase in "Title"s unit sales in the United States, helping it rise seven positions to number five on the "Billboard" 200 that week. Trainor climbed from number seven to number four on the "Billboard" Artist 100 as a result. Joe Lynch of "Billboard" described the rendition as "one of the night's quiet victories: Not a show-stopper, but a performance that stuck with you".
