You can't really beat Lady Gaga's appearance at last year's CES festivities, but the 2011 expo is proving to be quite the hot spot for celeb sightings, especially those who are endorsing products.

Our favorite honorary geek, Lady Gaga herself, will be on hand to debut her Polaroid "Grey Label,", the project which was announced at last year's CES. Alongside Gaga, 50 Cent will be on hand to introduce his new Sleek Audio headphones, while classic soul and funk legends Earth, Wind and Fire will be taking the stage at the Monster Awards party at the Paris hotel. (Don't make that face — they're one of my favorites.)

Who else will be gracing the CES expo hall and surrounding hotels? Find out after the break.

John Mayer and Lauren Conrad teamed up in NYC last night for Save The Music's annual gala. The organization, which is dedicated to restoring and preserving arts education in public schools, has long been a philanthropic cause close to John's heart. He, along with John Legend and Julie Andrews, was honored for continually supporting their work. Lauren Conrad, meanwhile, made a cameo to introduce Natasha Bedingfield, who sang the theme song from The Hills. LC managed to escape to the East Coast for the evening during a break from her acting and reality star duties. Good Charlotte's Joel and Benji Madden were together to pose for photos near Twilight's Billy Burke, though his fictional daughter, Kristen Stewart, was off getting down to business with Robert Pattinson in Brazil.

Kanye West traded in his red suit for a formal tuxedo at the GQ, Rocawear, and Hennessy Black party at the Gansevoort hotel in NYC last night. Jay-Z toasted the crowd and his sister-in-law, Solange Knowles, who was busy spinning tracks behind the DJ booth, while Kanye hung with his rumored muse, Selita Ebanks. Earlier in the evening, Kanye screened the 40-minute video for his new single, "Runaway," which he debuted at the VMAs last weekend. On Monday, he also joined Jay-Z and Eminem on stage during their first sold-out Yankee Stadium show. Entourage star Adrian Grenier made a quick appearance and snapped a few of his own photos at this bash and HBO's Boardwalk Empire event. Jay-Z partied without Beyonce, who had a huge week with a surprise catwalk moment and duets with her husband.

Harley Pasternak is a busy guy. In about the span of a week, he left his training duties on the Lady Gaga tour in Europe, headed home to LA to see 10 clients, and then crossed the Pacific to Hawaii for two more. When I finally caught up with him in Tampa, he was already planning his departure to Toronto, his childhood home.

Harley — whose client list reads like a who’s who of Hollywood — never expected that he’d become THE go-to trainer for the stars. "I was studying to be in medicine," says Harley. "Personal training was something I did; it was a side business that grew and grew and next thing you knew I had three studios and 12 trainers and I was like, 'OK, I guess this is my career.'"

He describes his work as "the coolest thing in the world," and it’s easy to understand why. Not many people can say they shoot hoops with Kanye West and Common or hang backstage with Katy Perry, Alicia Keys, and Lady Gaga. Working with musicians seems to be his current thing right now, "They’re very creative people, they have more control over their own destiny to the extent that they tend to be a little more stable," says Harley. "I enjoy working with actors too but actors are more project-to-project where musicians have an ongoing thing."

Harley pulled back the curtain a little bit and shared with me what it was like to work with these amazing artists. To see what he had to say about each one of them, read more

Queen Latifah may not be the most critically-acclaimed actress, but there's no denying that the woman's likable. In her upcoming film Just Wright, she plays a physical therapist named Leslie Wright who treats an NBA star (Common) to bring him back to peak condition. Her closest friend Morgan (Paula Patton) takes a liking to him and they begin dating until Morgan realizes his career (and baller status) is in jeopardy and bails. Leslie is there to pick up the pieces, but as she gets closer, things take a romantic turn.

I know it seems like I just gave the whole movie away, but trust me, it's all in the trailer. It's a formula really: Latifah is the tough (but sensitive!) career woman who can't find the right man; her inspirational song "Champion" playing in the background. That doesn't mean it won't rope me in though, at least as a rental later on. Take a peek, and tell me your take when you read more
