Taylor Swift certainly knows how to roll out the red carpet when it comes to her tours.When she was on the road for 1989 back in 2015, John Legend, Justin Timberlake, Mick Jagger, and Fifth Harmony were just a handful of the major artists she brought out along the way, and her Reputation outing is shaping up to be no different.

Barely a month into the mammoth 50-plus date stadium trek, stars like Shawn Mendes, Troye Sivan, and Selena Gomez have all popped up onstage, while celebs including Lena Dunham, Sarah Michelle Gellar, Amber Rose, and yes, even science icon Bill Nye have made appearances behind-scenes. Plus, don't forget that video cameo from funny-woman of the moment Tiffany Haddish.

Add that to some stellar costume changes, cinematic set design, and a few hater-shading props, and it's safe to say Swift has a hit on her hands.

Below, see photos of all of her celebrity guests so far. The Reputation tour continues Friday, May 25 at the Sports Authority Field in Denver, Colorado.
