ENGLAND soccer hero Frank Lampard enjoyed a late-night date with a sexy brunette — BEHIND locked hotel doors and BEHIND the back of his doting fiancée.Less than 48 hours after arriving in America's sin city Las Vegas on a boys-only jaunt, the Chelsea star led the beauty off to his luxury hideaway, leaving trusting lover Elen Rives in the dark back in London with their two children.
The Chelsea midfield star picked up the woman, a glamorous East European in her late thirties, at a blackjack table in the casino of the plush five-star Wynn hotel.
After the couple spent more than two hours alone in a suite together, grinning Lampard emerged with his arm around her about 2am.
As they strolled back to the gaming tables Lampard looked about, then tenderly stroked the girl's shoulder before kissing her goodnight on the cheek and heading off to find his pals.
But just minutes later the beauty's smiles turned to sobs when the News of the World told her the truth about her dashing 29-year-old date.
With tears streaming down her face, she said: "I had no idea he was a rich footballer and he didn't tell me he had a girlfriend and two daughters.
"This is terrible. I don't know what to do. This is a nightmare."
Lampard — set to become the best-paid player in the world with a new £135,000-a-week contract — jetted into Vegas on Wednesday lunchtime with team-mates Shaun Wright-Phillips, 25, Wayne Bridge, 26, Glen Johnson, 22, and other friends.
Within hours the boys were downing beers and hitting the card tables at the Wynn.
On their first night they entertained scores of women in a private cabana at the trendy Tao nightclub before returning to their hotel alone. On day two Lampard - 5,000 miles away from home — made his cheeky move.
After a day drinking and sunbathing at the Hard Rock Hotel the boys — now joined by Teddy Sheringham — were at the Wynn casino again. Within an hour of sitting down at a high-stakes blackjack table it was clear Lampard had his eye on something other than the cards.
Sitting directly behind him at the next table was the attractive brunette dressed in a slinky, brown floor-length dress. Lampard could not keep his eyes off her.
Soon the pair were chatting and flirting and the woman switched to a seat alongside.
Another guest told us: "There was an obvious chemistry between them. Until spotting that girl he was concentrating on his hand and winning quite a bit of money. All the lads were betting at least £100 a time. But as soon as Frank clocked her his interest faltered.
"He's a complete charmer. Soon they were leaning in close, nuzzling their heads together and giggling. None of his buddies batted an eyelid.
"It was like they were used to it. They didn't even look shocked when just before midnight Lampard suddenly got up after whispering something in the girl's ear."
Lampard then walked off across the room with a burly guy, believed to be a bodyguard.
The girl followed nervously just 30 yards behind. The minder led them down a deserted corridor. After a look back he took a key card from his pocket and led the pair through a door marked "Fairway Suites" — a luxurious complex of £2,000-a-night rooms.
Seconds later the guard came back out alone. Lampard and his stunning new lady friend were left to their own devices.
The shock revelations come less than TWO months after lover Elen gave birth to their second daughter Isla — and nine months after he was caught cheating with a blonde in Barcelona.
In 2000 the News of the World revealed how Lampard and other stars lured girl fans into a Cyprus hotel orgy captured on video. He later admitted his shame and said: "I should never have put myself in such a compromising situation,"
