Britain's Got Talent winners Collabro top the albums' chart with their debut release Stars, putting an end to Ed Sheeran's eight-week reign at the top.
The French DJ and producer Guetta said he was delighted with his latest chart success.
He told the Official Charts Company: "Wow, this is amazing! The UK has shown me so much love and support over the years, since I was an unknown DJ there. To be number one with the first song off my next album is taking a little bit of the pressure off finishing it, which is what I'm doing now."
He has sold nine million singles in the UK.
Am I Wrong by Norwegian duo Nico and Vinz fell to number two, while Rude by Canadian band Magic! dropped a place to three.
