Geldof reveals pain over Yates' death
The musician made a tribute to Yates, who was found dead at her home in London having taken an overdose in 2000 on the third anniversary of Hutchence's suicide.
Geldof said: "You live this life for this great 20 years - she was brilliant, funny, gorgeous and I loved her very much.
"And then she falls in love with someone else. Like everyone else in that situation, you find it very hard to understand and yet you have to - and then there are the nightmares and horrors that follow.
"You can imagine, you lose the person you love once and then you lose them completely, utterly, totally."
Geldof, who married Yates in 1986, split up with the former Big Breakfast star in 1994 after she started her affair with the INXS rocker.
Hutchence was found hanged in a hotel bedroom in 1997.
