A boy has died after falling from the balcony of a Spanish apartment while on a holiday with his mum and a friend.
Lucas Briscoe, 12, from Lostock Gralam, Cheshire, was due to return home after a two-week break in the Costa Del Sol resort of Fuengirola when he fell on Tuesday afternoon.
His death is being treated as an accident.
"I can't believe he's gone. He was my world," said his mum Nicola Marshall in tribute to her only son.
"Please grab your child and cuddle them today and tell them how much you love them because they're precious and you never know when tomorrow will never come," she added.
Lucas, a talented singer and rugby player, went to St Nicholas High School in Hartford, Northwich, and had been due to audition for TV talent show The Voice this weekend.
Lucas, his mum and his schoolfriend had been staying in a holiday apartment owned by Lucas's father, and Ms Marshall's ex-husband, Gary Briscoe.
"What should have been the final day of an amazing holiday ended up being the worst day of my life," said Ms Marshall, who was in the kitchen preparing lunch when Lucas fell at 13:30 local time.
His friend witnessed him fall and has been left "devastated", a family spokesperson said.
"We had the usual complaints over hoovering and cleaning…all the usual chaos before you go home," Ms Marshall said.
"I lost my world, my everything, when Lucas went over the balcony. A fall, a jump, a slip, a moment of silliness, boyish behaviour, annoyed at his mum for nagging him over hoovering. I will never know.
"What I do know one million per cent is that if Lucas had truly known the repercussions of climbing over, he wouldn't have wanted that. He wouldn't have wanted to leave this world. Not yet."
Mr Briscoe, who has flown out to Spain, said: "I am devastated. No-one expects to say goodbye to a child and not in circumstances like this. We are devastated at losing our precious, vibrant and loving son.
"Lucas was a memorable character - funny, outgoing, sociable - he is going to leave a big hole in a lot of lives."
A Foreign Office spokesman said it was offering support to the family and is in contact with the Spanish police.
