Perhaps it's just to release stress or just the thousands of taut and toned physiques on show but expect plenty of free love at the Olympic Village at the upcoming London Games.

At least that's if history repeats itself.

US Olympic gold medalist Hope Solo, who recently gave an insight on what went on the behind-the-scenes during her two-week stay at the Olympic Village back in 2008 in Beijing, said there's "lots of sex going on".

The 30-year-old goalkeeper, who will be heading to the London Games with the US women's national football team, told ESPN in an interview, "With a once-in-a-lifetime experience, you want to build memories, whether it's sexual, partying or on the field. I've seen people having sex right out in the open. On the grass, between buildings, people are getting down and dirty."

Apparently, she's not the only one who's seen the "down and dirty" side of the Olympics.

US swimmer Ryan Lochte believes "70 per cent to 75 per cent of Olympians" hook up behind the scenes, adding "Hey, sometimes you gotta do what you gotta do."

There was so much action at the Games that even celebs joined in the fun with the athletes.

Solo said, "I probably shouldn't tell you this, but we met a bunch of celebrities. Vince Vaughn partied with us. Steve Byrne, the comedian. And at some point we decided to take the party back to the village.

"We started talking to the security guards, showed off our gold medals, got their attention and snuck our group through without credentials -- which is absolutely unheard of."

"I may have snuck a celebrity back to my room without anybody knowing, and snuck him back out," Solo added. "But that's my Olympic secret."

Singapore will be sending 23 athletes to the London Games.

Thousands of competitors are now descending upon the Athletes Village and training camps ahead of the Games which start on 27 July.

About 17,000 athletes and officials are expected to live at the village, which is located inside the Olympic Park and close to main stadium and swimming venue.

Let the fun begin.
