Coachella is one of the most popular and star-studded music festivals in the US (think Glastonbury but with more sun and much less mud).

The event, which started in 1999, takes place over two weekends, and previous acts include Red Hot Chili Peppers, Beastie Boys, Florence and the Machine, and Snoop Dogg, to name a few.

2014's line-up promised to be a pretty special year, with Muse, OutKast and Arcade Fire all billed as the headliners. And, as with every other year, guests were treated to a lot of surprise performances and impromptu appearances (which is one of the best reasons to attend it, we reckon).

This time the likes of Jay Z, Gwen Stefani and Beyoncé (SCREAM!) all popped up where they weren't expected. So, with this in mind we've taken a look at some of the coolest things to happen at Coachella so far. If you weren't there, prepare to feel very jealous indeed.

Beyoncé and Solange dance together

Just when we thought a Tupac hologram couldn't be beaten, Beyoncé joined little sister Solange on stage for a dance routine. That's right, she didn't even need to sing and she brought the house down.
