We already knew Haim's new video for the remix of 'My Song 5' was going to feature SNL's Vanessa Bayer, but it turns out that was just the tip of the celebrity iceberg.

The ladies of Haim portray guests on a Maury Povich-style daytime talk show hosted by Bayer's character, Dallas Murphy, setting the stage for a veritable 'Where's Waldo?' of other musicians, actors and even Haim's parents and producer Ariel Rechtshaid.

Kesha portrays a woman in love with her cat, Vampire Weekend's Ezra Koenig is an unimpressed audience member, Artemis Pebdani from 'It's Always Sunny in Philadelphia' plays a woman afraid of cotton balls, Grimes talks with Danielle Haim in the waiting room and A$AP Ferg (who raps in the remix) shows up as a man whose girlfriend dumps him for another woman. Big Sean is in there, too.

It's clear that Haim hit it off with Bayer when they appeared on her web series, 'Sound Advice,' last month. Check it out below.
