Justin Bieber serenaded a record number of fans during his Valentine's Day TikTok livestream, drawing more than 4 million unique viewers over two broadcasts on Sunday and Monday, according to Def Jam. That makes his "Journals Live" performance the most-watched single-artist livestream ever for TikTok.

The livestream marked a few other milestones too: It was the first full-length single-artist live performance on TikTok and it was the first time Bieber had performed his 2013 project Journals.

The super-personal, R&B vibe of the fan-favorite album was a perfect fit for Valentine's Day, as evidenced by the TikTok viewership and the boost in streams after. On-demand streams of Journals' songs increased 37% in the U.S. on Feb. 14-16, according to initial reports to MRC Data. The album's collected tracks garnered 1.32 million streams on Feb. 14-16, versus 963,000 on Feb. 11-13.

Bieber also saw a spike in TikTok followers, increasing by 700,000 to 20.3 million after the announcement of the Journals livestream.

"Journals is one of my favorite projects and I’ve never performed it live,” Bieber said ahead of Sunday's broadcast. “I’m grateful to TikTok for helping me to bring this show to everyone on Valentine’s Day."
