The latest in the seemingly never-ending pool of celebrity sex tapes involves Farrah Abraham, one of MTV's "Teen Mom" stars who hired porn star star James Deen to shoot a "home video" with her. We all scoffed at her shameless ways-but today it was confirmed that she sold the video for $1.5 million.

Of course, a huge sum of money doesn't make an act like this okay, but celebrity sex tapes have been big business for years. While many only seem to remember recent examples like Kim Kardashian and Paris Hilton, there actually have been a number other (and not so famous) stars who have had their intimate business released for the world to see. And, in some cases, they've even released the tapes themselves, like Abraham.

Would you pay $529 to be at this wedding? (Photo: Getty Images)According to an American Express survey of 1,518 people, guests will spend an average of $539 per wedding this year—and that's just to attend the event, not to be a member of the wedding party. The wallet-busting figure is up $200 from 2012, when guests reported shelling out an average of $329 on clothes, hotel rooms, and gifts.

The real cost is probably even higher given the estimates for some of the costs. The credit card company says that guests will budget just $57 for new clothes, $27 for a babysitter or pet sitter, and $95 for a hotel room—all of which seems astoundingly low, even for a local event. Members of the bridal party can count on spending a little bit more, thanks to slightly higher clothing costs: about $577 per wedding, according to American Express.

"Waiting to be Heard"

From the very beginning, the tabloids dubbed Amanda Knox (who was twenty at the time of her arrest) "Foxy Knoxy." Last year, lad mag Maxim, even awarded her the dubious honor of being on their "Hot List" of the world's sexiest women. Her new book, Waiting to Be Heard, which includes a frank discussion of the fact that she had casual sexual encounters as an exchange student in Italy (as well as smoked pot), has once again tweaked the libidos of the press who are treating it less as a tale of destroyed youth and entrapment in a terrifying web of judicial incompetence and more as the next installment of "50 Shades of Gray."

Knox was arrested in 2007 (along with her Italian boyfriend) for the sexual assault and murder of her roommate, Meredith Kercher, in Perugia, Italy. Prosecutors portrayed the incident as a botched Satanic sex ritual. She was convicted in 2009, and her sentence was overturned in 2011—only to be reversed in late March this year. Her own account of the events was

Spending quality time with your bridesmaids is often one of the happier parts of wedding planning, but it's normal to have the occasional disagreement with your ladies, especially when tensions are running high. That being said, there are instances when a 'maid, or maid-of-honor seriously shirks on her responsibilities, and when this happens, can you ask her to resign from her duties?

While it's within your rights to "fire" her, this will likely end your friendship. Instead, try talking to her first. You may end up cutting her some slack. She might be so overwhelmed with work or life issues that her wedding duties are taking a back seat. Another option is to let her step down of her own accord. You could say, "I don't want to force you to do anything that makes you unhappy, so please let me know if you're not up for this. I won't hold it against you."

Sarah Dill and her boyfriend Ben.Online dating comes in many forms. But who knew a Web site as salacious as Chatroulette could render a real relationship? Sarah Dill, a senior at New York's Fashion Institute of Technology, shares her sweet story of how her now boyfriend went from Internet stranger to man of her dreams. As told to Dara Adeeyo.

It started on February 19, 2012 when I was hanging out in my friend's dorm room. It was late and her other friend popped open her laptop and suggested we go on Chatroulette just for fun. I had never been on the site, but always thought it was a place where most people only had the intentions of flashing their goods. (Chatroulette is a place where you can interact with random strangers around the globe via Webcam.)

We got started and crossed paths with some pretty, um, interesting people: A super drunk dude with a British accent, and so, so, sooo many weird men dancing (what's up with that?!). Several sudden clicks later, we came to a guy with a guitar named Ben.

The Chandler effect.Sorry, Chandler. Today in studies we completely disagree with, UK social researchers have discovered that while funny guys are often the first to get laid, they're the last to be chosen to, say, meet her mom or pick out shower curtains with her at Crate and Barrel. That is to say: Ladies don't want to get serious with dudes who are funny, according to Metro UK. Boo.

The study filmed 40 psychology students - half men and half women - answering a basic hypothetical question. Nineteen students whose answers contained humor were termed "actors," and their videos were played for the following students, who were asked to rank them in terms of suitability for a short-term relationship (as short as a one-night stand, in fact) or a long-termone. Based on the answers, the researchers determined that male wit "nurtures an impression of not being serious or willing to invest in a mate."
