Decked out in a tight-fightting, straples purple dress that showed off all her curves, Leona Lewis played hostess at the private party held at Hyde in Hollywood to celebrate her new album, ECHO, sponsored by ASICS.

Other musicians made their way congratulate Leona on her latest endeavor such as former NSYNC members, Justin Timberlake and JC Chasez, Ciara and Eve. In fact, the "SexyBack" singer was spotted pushing his way through the throng of fans to make his way to the X-Factor winner to congratulate her personally with a hug and a smile.

Ciara showed of plenty of leg in her Jeremy Scott dress, aided by her Christian Louboutin high-heels and Eve also stepped out in a flirty black frock, showing off some sheer fishnets and white pumps.

From the title of his film, The Social Network, it would be hard to guess that Justin Timberlake's movie project actually a comedy. However, producer for the film, Kevin Spacey, confessed to MTV News, "It's probably going to be a lot funnier than people might expect it to be."

The story focuses on the founders of Napster and Facebook, so on paper, it sounds like some pretty dry subject matter.

You would hardly guess from the serious facial expression Justin is wearing on set, making his way to film scenes of the film. But then again, we all know how easily Justin is able to turn on that funny switch whenever he's guest-starred on Saturday Night Live. Maybe there's a surprise dick in a hard drive?

Justin Timberlake seen on the first day of filming his new movie about the Facebook craze, called The Social Network. Timberlake plays the part of Sean Parker, a Napster co-founder who helped Mark Zuckerberg grow Facebook after its launch at Harvard.

After assuming the mantle of Facebook president, Parker was forced out after a falling out with founder Mark Zuckerberg, played by Jesse Eisenberg, in what was just one of the many personal squabbles and breakups shadowing the company in its early years.

Doing their best to keep breakup rumors at bay, Justin Timberlake and Jessica Biel walked hand-in-hand to take in the Jay-Z concert at the Pauley Pavillion in Los Angeles. The couple appeared somber as they marched their way past paparazzi.

Always one to have a gorgeous lady on his arm, James Blunt showed up with a mystery blond sporting bright red lipstick and a smile.

DJ Samantha Ronson was flying solo to the event, as was mother-of-two, Nicole Richie. It's nice to see that Nicole is still sporting some post-baby curves, while Samantha is still looking skinny as ever.

As if we didn't already know, Justin Timberlake is not just a super star, he is also a SUPER STUD. Not only is Justin "with" one of the hottest women in Hollywood, the bootylicious, although reportedly clingy, Jessica Biel, as well as rumored to be hitting the sexy fierceness that is Rihanna, he has to take legal action against zealous, crazy, old women who are also after the junk in his trunk. Luckily this time, I do not mean Cameron Diaz.

In court documents requesting a restraining order filed Friday in Los Angeles, Justin's unwanted visitor, Karen McNeil, is described as a "heavyset white female, approximately 50 years of age", who also "appeared to be a transient." Also noted was how she was able to bypass security measures and "trespassed onto [Timberlake's] property, attempted to gain access into his home, and delusionaly claimed to know and be friends with [Timberlake]."

Imagine waking up to that big ball of crazy smiling next to you in bed in the morning. 2 words Mr. Studdy Mc Timberlake: Guard Opossums...Guard Opossums.

Take that breakup rumors! Justin Timberlake reunites with girlfriend Jessica Biel in Vancouver, where Jessica is shooting The A-Team.

Biel and Timberlake had reportedly broken up a couple weeks ago but as these photos show they are still going strong! I'm assuming that the looks on their faces are due to the fact that they are trying to avoid having their photo taken.

Although rumors have been running rampant surrounding the alleged break up of Jessica Biel and Justin Timberlake, Justin's mother Lynn Harless begs to differ.

When asked what kind of girl would be best for her son, Lynn told E News that "the one he's with now is awesome." According to Momma Timberlake Justin has "found someone that'll golf with him, give him a hard time when he deserves it, and stand up to him."

While these are all great qualities, it looks like Lynn's hopes have yet to come to fruition. Justin was spotted solo on a recent trip to Las Vegas to host a celebrity golf tournament for Shriner's Children's Hospitals.

While Jessica was no where in sight, Justin was joined by stars that included Alicia Keys, Jay Sean, Ciara, and Taylor Swift.

This past Saturday night Justin Timberlake had a little get together. Timberlake invited eight so-called "friends" to join him onstage: Snoop Dogg, Taylor Swift, Alicia Keys, TLC, Timbaland, Ciara and Jay Sean.

The benefit concert was all for benefiting Shriners Hospitals for Children and was held at Mandalay Bay Hotel & Casino in Las Vegas.

The night saw Justin wearing many hats (including a fedora) -- acting as emcee, performer and maestro. He even kept the crowd updated with the Yankees/Angels score in between sets. But the fans were there for music, and they sure got their money's worth.
