Michael Phelps (23) is will release his book Built to Succeed on December. The book will tell the story behind his historic eight gold medal swims, which resulted in seven world records.

Will you buy it?

The answer is Nastia Liukin (right) and Shawn Johnson (left). The question is:

Which two perky Olympian teammates are really bitter rivals? One spiked the other’s protein shake with laxatives before a big competition, but her plan backfired when her nemesis not only powered through the competition but beat her so-called friend anyway.

It’s hard to say who did what since Nastia beat Shawn in one competition, and Shawn beat Nastia in another. Both took home gold and silver Olympic medals.

Michael Phelps (22) will make an estimated $100 million, or more, during his lifetime due to his win of 8 gold medals during the 2008 Beijing Olympic games. Overall Phelps has won a total of 14 gold medals in his career. Phelps beat Mark Spitz (58) 1972 record of 7 gold medals won at an Olympic games.

With the fame comes curiosity about his personal life, and accusations of cheating. One advantage Phelps, and others had, was their special Speedo suit, which simulates dolphin skin, and helps the swimmer glide through water with little resistance.

Extra interviewed Phelps and told him Carrie Underwood has a crush on him. Phelps responded:

"That’s the first I’ve heard of that. That’s pretty cool."

Extra also asked if he was dating Amanda Beard (above), Phelps said:

"No, I’m not dating Amanda Beard. I’ll say that. I think she has a boyfriend."

He was then asked if he is single:

"Part of my life is kept to myself. I’m able to relax and be with my friends. Those pretty much are the only people who really know the answer to that question."

There are rumors that Phelps is dating Lily Donaldson.

Phelps was also asked about the big bucks he’ll be making in endorsements:

"It’s not about the money. I love what I do. The one thing I’m really looking forward to doing is raising the bar in the sport of swimming and promoting it to get new faces involved in the sport."

It’s about winning, being the best, and the money. With all that, Phelps can help young people get their start in swimming.

Being number one has it’s perks, like when Michael Phelps got to meet Vanessa Minnillo on MTV’s Total Request Live (below).

Phelps appears, as many Olympic gold medalists have, on the cover of Sports Illustrated, but he won’t be on the Wheaties box. Instead, Phelps will appear on Kellog’s Corn Flakes and Frosted Flakes boxes, which will come out in September.

Even Michael’s mom, Debbie Phelps, is now a celebrity. Johnson’s Baby has dubbed Debbie their Mom of the Olympic Games, and the company will donate money in her name to children’s causes. Debbie said Michael was diagnosed with ADHD when he was nine:

"He was non-stop, always going, always questioning," Debbie says. "When the teachers brought it to my attention about his lack of focus in the classroom, that’s when I got concerned."

"When he was nine, 10, 11 years old, he would sit at the pool for hours. That’s why when I was talking with his teachers, and they’d say, ’He can’t focus on anything,’ I’d say, ’Well yes he can! He can focus on the pool.’ He was able to focus on what he loved."

Thanks to the support of his mother, hard work, and determination, Michael Phelps is now an example to people all over the world.

Usain Bolt, who is from Jamaica and is nick named Lightening, set a new 100 meter world record of 9.69 seconds winning the first gold medal ever for his country. He is something like 6 feet 5 inches tall, and he even slowed up at the end, so we don’t know how fast he could have really ran the race. Bolt reminds me of a race horse with those long legs. The race was amazing.

Michael Phelps won his eight gold medal on Sunday, breaking Mark Spitz’s record.

Dara Torres, who is 41 years-old, and a five-time Olympian, is now the oldest American swimmer ever. Torres won two silver medals on the final day of swimming at the Water Cube, and lost a gold medal Sunday morning by one-hundredth of a second.

The 2008 Beijing Olympics was one of the most amazing and inspiring.

On June 24 David Beckham will attend the closing ceremony to mark the transition of the Olympics, which will help held 4 summers from now in London.
