A year in the life of a celebrity would not be complete without a sex tape or a nude photo scandal, so RadarOnline.com has compiled a list of Hollywood's most salacious stories involving celebs in their skimpies in 2011.

Nude photos of actress Scarlett Johansson hit the Internet in September after her cell phone was hacked. The 26-year-old beauty anted up a couple months later admitting they were her, but were taken years ago for then-husband Ryan Reynolds. “There’s nothing wrong with that," she said. "It’s not like I was shooting a porno -- although there’s nothing wrong with that either.”

Other starlets such as Jessica Alba, Christina Aguilera , Miley Cyrus and Vanessa Hudgens were also victims of having personal nude photos leaked onto the web, causing the FBI to launch an investigation into a group of hackers, eventually arresting 35-year-old Christopher Chaney on charges of wiretapping and identity theft.

In January, Jersey Shore star Jenni "J-WOWW" Farley won a legal battle against ex-boyfriend Tom Lippolis, who wanted to release naked photos of the reality TV starlet. "Before she had her second breast augmentation, she was uneven, scarred, deformed and had tons of cellulite," Tom told RadarOnline.com.

Kanye West's ex-girlfriend Amber Rose had naked photos of herself leaked onto the Internet in February featuring several pictures of her with her breasts exposed through her clothes, and others of her completely naked.

Tinsletown ladies aren't the only ones wrapped up in nude photo scandals, as we learned in 2011, athletes and politicians like to snap X-rated photos of themselves too. Philadelphia Eagles star Michael Vick had to go on the defensive when a woman claiming to have "full frontal" photos of him was shopping them around to various media outlooks looking for financial compensation.

And former congressman Anthony Weiner was disgraced earlier this year when he posted a photograph showing a close-up shot of a man's bulging crotch, on his Twitter account addressed to 21-year-old college student Gennette Cordova. After the scandal broke numerous women across the country came forward claiming the married man had "sexted" them over Facebook or phone.

As for sex tapes, Kendra Wilkinson, Tila Tequila and Rihanna had that market cornered.

It was revealed in January that ex-Girl Next Door star Kendra had done a sex tape with a girlfriend named Taryn Ryan. "They were friends and were hanging out together, with their boyfriends," a source close to the situation exclusively told RadarOnline.com. "It's a long tape, about 45 minutes. And there is nothing left to the imagination."

Internet sexpot Tila has struggled with keeping numerous sex tapes under wraps, winning the rights to a tape she made with ex-boyfriend Francis Ten in January — and then by February a sex tape featuring the pint-sized star romping with two girlfriends leaked onto the web.

And finally, RadarOnline.com exclusively reported in August that porn magazine Hustler had obtained a sex tape featuring singer Rihanna getting frisky with rapper J-Cole. "Hustler is in possession of the Rihanna and J-Cole tape," said a rep for the adult company. "We have seen it and we do not know what we are going to do with it yet." Luckily for the sexy Caribbean queen, she escaped 2011 without the tape being released.

The President of a national Italian American group has branded Nicole “Snooki” Polizzi as the country’s worst ever export after she crashed into an Italian police car this weekend.

UNICO President Andre Dimino exclusively told RadarOnline.com: “She really is the lowest of the low and will do anything for attention, even hitting a police car."

“She is our worst ever export and is an embarrassment for Italian Americans and our whole country."

“For MTV to go and film in Italy was totally ill conceived, and this latest incident has just added insult to injury as far as I’m concerned."
