British-Lebanese performer Mika returned to Los Angeles last week to prove that he still has it. The audience were treated to a night full of antics and happy music, much to their delight. Mika has just released his second album, but also performed a lot of songs from his debut album.

It’s like a Bono humanitarian concert for teens and tweens. We Day is an annual youth empowered rally by Free The Children, an organization that aims to fight child labor. This year, We Day started out in two different venues and dates in Canada—September 29 at Vancouver’s GM Place and October 5 at Toronto’s Air Canada Centre. The third and final set will be on November 5 at the Hamilton Place.

Some 16,000 students and teachers attended the musical event. Guest performers such as The Jonas Brothers, Justin Bieber, Hedley and dancers from So You Think You Can Dance Canada were received with ear-splitting cheers from the crowd.

The event wasn’t just about a cool concert. The kids and teens in attendance were in full support of the organization’s cause—to make tangible actions that make a better world, especially for children. Humanitarians, environmentalists, motivational speakers and politicians were greeted like rockstars at the event.

SOS call: The Jonas Brothers made a surprise appearance.

Justin Bieber performed the acoustic version of his hit “One Time” at We Day.

“We share with our team and we truly believe it’s not about us. It’s about the issues and we share that with all the young people,” said Marc Kielburger, one of the founders of Free The Children. “We’re just happy that the young people feel that it’s really cool to get socially engaged and what we’re fighting most of all is we’re fighting apathy.”

“Everyday action is our message and people respond to that message because they’re really searching to bring about a positive change in this world,” added co-founder Craig Kielburger.

With the success of the rally, it looks like the kids heard the message loud and clear.

The best place for celebs to show off their hot designer duds is in the VIP section of fashion shows. Check out these Hollywood fashionistas who managed to steal the attention away from the catwalks at the Paris Fashion Week Spring/Summer 2010. Who wins your vote for best dressed?

Rihanna attended the Jean-Paul Gaultier Pret a Porter show wearing a daring cutout number. Accompanying her at the fashion shows is stylist Mariel Haenn.

She also managed to keep her hands warm in a jewel-encrusted Chanel muff in the French designer’s show.

Dita Von Teese arrived at the Christian Dior show in her signature old Hollywood glam look.

Supermodel Claudia Schiffer went for military chic at the Chanel Pret a Porter show.

It’s in the jeans. Gwyneth Paltrow kept it casual at the Stella McCartney show in Palais De Tokyo.

Katy Perry went hot for sequins at the Sonia Rykiel show. To the surprise of her fans, she ditched her usual colorful retro wardrobe and went for a darker look.

Lindsay Lohan (right) and Spanish designer Estrella Archs walked the runway for Emmanuel Ungaro. Lohan was introduced as the fashion brand’s artistic director, much to the dismay of critics.

Singer Prince outshone the other men (and women!) at the Grand Palais for Chanel. His sexy high heels will put any catwalk diva to shame.

Rocker dude meets boho chick. Couple Max Snow and Mary-Kate Olsen attended the Giambattista Valli Pret a Porter show as part of the Paris Women’s Wear Fashion Week in Jardin des Tuileries.

Lily Allen (right) gave a surprise musical performance at the Chanel Pret a Porter show. She popped out from a pile of hay to perform her hit song “Not Fair.”

The Material Girl thinks that other performers are out to copy her moves. She says that J-Lo was at her concert and watching her super closely – probably wanting to pick up a tip or two. I think she should be flattered!

The celebrity couple are taking collaboration to a whole new level. They are the hosts to the upcoming Nobel Peace Prize Concert in Oslo. The show will take place on December 11 and will also feature a host of performers. Why the couple? Organizers say they are the perfect ambassadors for peace. I wonder what the Jolie-Pitt brood are thinking.

In last year’s Emmys, five reality stars emceed the show. It was so disastrous that I forgot who they were, and I supposed, so did you. And boy did the producers make up for it this year! TV actor and Broadway star Neil Patrick Harris was hailed for his superb hosting skills and opening performance at the 2009 Emmy Awards.

Reminiscent of his Tony Awards performance this year, NPH’s opening act was a song-and-dance number that didn’t disappoint. Never mind that he didn’t win Best Supporting Actor for How I Met Your Mother. If you missed it, view it here:

His hosting was so good that when Jeff Probst accepted his award for Best Reality Host for Survivor, he said in his acceptance speech: “Neil Patrick Harris, THIS is how you host the Emmys. Nice job.” Now I remember. Jeff was one of the five hosts in last year’s show.

If that wasn’t enough, Jon Stewart, who accepted the Best Variety, Music or Comedy Series award for The Daily Show, paused in the middle of his speech to compliment NPH on doing a great job.

As for the winners that night, there wasn’t much surprise as most of the awards were given to the same winners as last year’s Emmys. See the full list here.

“The Emmy cast with Harris in charge not only was remarkably stylish, fun and brisk but could even make viewers forget last year’s disastrous format with five hosts, none of whom could rise to the occasion,” commented Frazier Moore of the AP.

First the Tonys, and now he saves the Emmys. What’s next for NPH—the Oscars?

Controversial singer Amy Winehouse has been flying below the radar for a while, and she surprised the audience by joining The Specials on stage at the V Festival in Chelmsford, England.
