HE only wanted a quiet night out - but poor James Bourne ended up in a series of unprovoked Bust-ups instead.

First the 20-year-old former Busted singer clashed with gobby rocker Kelly Osbourne.

Then he was left fuming as his old foe F1 driver Jenson Button muscled in on a girl he had his eye on.

And then he narrowly avoided injury when a bottle was hurled at his head.

The evening started well when James turned up at London club Umbaba with McFly's Danny Jones and some other pals last week.

But things went downhill when he was confronted by Ozzy's daughter, who clearly had a score to settle.

Busted very publicly fell out with Kelly last December after she said in an interview: "They've all got acne and wear more make-up than I do... They're the stupidest, most ridiculous fools ever."

Charlie Simpson hit back by sniping, "Her dad is a legend. She's not."

And Matt Jay added more fuel to the fire with, "I'd smack the living daylights out of Kelly Osbourne if she turned into a man."

So sparks were bound to fly when she actually came face to face with one of Busted.

According to our source: "Kelly came right up to James and said, 'Have you been saying bad things about me?'

"He said he had nothing against her and wanted to put their 'beef' behind them."

While trying to calm Kelly down, James spotted race ace Jenson Button across the room.

James is friendly with Jenson's ex-fiancee Louise Griffiths - he used to date one of her friends - and consoled her when Jenson dumped her. So he wasn't best pleased to see Jenson chatting up a girl HE liked. Our spy adds: "James couldn't believe Jenson was there - hitting on the same girl he fancied.

"There's no love lost between them. James is very good pals with Jenson's ex, Louise, and saw how he broke her heart. So when Jenson tried it on with a girl he liked, he was understandably miffed."

Then a drunken reveller hurled a bottle in James's direction.

Our source says: "This girl tried to start a fight with Kelly. When that didn't work she stood on a table, kicked all of James's drinks over and hurled a bottle at him and his pals. It missed him by inches."

Things picked up after that, at least for Kelly. James invited her to a party in Whitechapel, East London, where she got cosy with McFly guy Danny.

Still, James can console himself knowing his career's on track - music biz insiders are tipping his new band, Son Of Dork, for great things.

So he's holding out for the Bourne supremacy - if he can keep out of trouble, that is...
