On August 17, 2017, Bieber released the single "Friends" with American record producer and songwriter BloodPop. Songwriters Julia Michaels and Justin Tranter reunited with Bieber to construct the song, just as they helped create his hit single "Sorry" in 2015 on his fourth studio album "Purpose". Bieber did not attend the 2018 Grammy Awards Show to perform the nominated song "Despacito", claiming that he would not make any award show appearances until his next album was finished. In July 2018, Bieber reunited with DJ Khaled in "No Brainer", co-featuring again with Chance the Rapper and Quavo. The single peaked in the top 5 of the Hot 100 and reached number one on "Billboard"'s Hot R&amp;B Songs chart. He was also featured in the accompanying music video.
