Longitude is on this weekend in Marley Park and we have your day one highlights.
Day one included acts such as Stormzy, Picture This and Dua Lipa.
Fans were posting videos online of some of their favourite acts.
Some Irish well known faces were also at the gig including Thalia Heffernon, Rob Lipsott and Rosie Connolly.
Earlier, organisers Festival Republic were forced to issue an apology after too many people arrived early yesterday, leading to a crush at the site. Check out the full story here.
