It’s hours short of 5:44 a.m., but Gwen Stefani has already surrendered the “Slow Clap†remix — now with 100 percent more Saweetie. Amen! Stefani first dropped the single a month ago, as the followup to January’s “Let Me Reintroduce Myself.†And just days ago, Saweetie — in a bounce back after her breakup from rapper Quavo — teased that she’d guest on a remix of the track, posting a shot from the new music video to Instagram. And speaking of, this video’s definitely less of a reintroduction, with the high school vibes throwing us right back to Stefani’s “Hollaback Girl†music video from 2004. Applause all around.
