WORLD'S fastest man Usain Bolt two-timed the British barmaid he secretly dated for a year - by bedding a care home worker from Swindon.

Fast worker ... track hero Usain Bolt

Curvy Gemma Jones, 25, last night told how the Olympics icon wooed her on TWITTER, sent her a snap of himself in his PANTS, then ROMPED with her at a London hotel.

Afterwards the superstar begged her for a foursome.

Gemma, who turned the randy sprint king down, said: "He certainly keeps up a good pace in bed.

"But I suppose that's not surprising as he's the fastest man in the world."

She had no idea a fellow Brit was Bolt's long-term lover until South East London barmaid Rebeckah Passley, 23, told in The Sun how he dumped her just a few weeks ago.

Dumped ... British barmaid Rebeckah

Rebeckah spent a year thinking she was the only girl in the Jamaican hero's life after he chatted her up at an athletics event.

Last night Gemma accused bedhopping Bolt, 24 - who holds the 100metres world record - of leaving her "heartbroken" too.

The pair "tweeted" via the internet for months before he invited her to his hotel in Mayfair on September 2 while in London plugging his book.

Gemma said: "It sounds like he had a girl in every city. I feel cheated."

Bolt from the blue ... raunchy request

Describing their romp, she said: "I wasn't wearing anything remotely sexy - leggings, a cardigan and grey boots.

"He seemed to find it a massive turn-on. He's a very good lover - I give him eight out of ten.

"He kept telling me how much he loved my bum. He's got a great athletic body, but he's average size in the trouser department."

Afterwards they showered together. Gemma said: "He told me all about Jamaica and I told him about Swindon.

"He asked me if the shopping was good in Swindon and I told him it wasn't great.

"Once he heard that he seemed to lose interest in Swindon."

Bolt, who invited her to spend Christmas with him in Jamaica, has since bombarded her with raunchy messages using his Blackberry phone.

Gemma said: "He asked me for a threesome and for a foursome. I'm not into that sort of thing and told him, 'No way'."

Last night shattered barmaid Rebeckah broke down sobbing as she said: "I don't want to say any more."
