Taylor Swift in concert (Splash News)Taylor Swift hit the stage in style (well, 10 styles, actually) to kick off her "Red" tour in Omaha, Nebraska, Wednesday night.

The 23-year-old country star seems to be shedding her good girl image, especially when it comes to her wardrobe. Among the many outfit changes, she sported a saucy, black corset-inspired jumpsuit that showed off her long legs and left little to the imagination. She also looked smoking hot in a daring red ensemble that was short in the front, long in the back, and totally fierce all around.

Check out the video to see all of her sassy concert looks, and be sure to catch "omg! Insider" on television tonight to see more footage from her amazing performance!

It looks like giving up her syndicated show wasn’t such a big deal after all. Almost two years after she called it quits on her talk show, Oprah Winfrey is still the most influential celebrity in America, according to Forbes.

According to data from E-Poll Research, 48% of people polled rate Winfrey as influential. That’s down only one point from last year when she also topped the list of Most Influential Celebrities. Ratings at Oprah’s OWN network are starting to creep up thanks to big “get” interviews like her recent special in which she grilled Lance Armstrong about his drug use. The two-part show drew 28 million viewers around the world. Prime-time ratings at the network are up 17% already this year, according to Nielsen.

On Wednesday’s "American Idol," Nicki Minaj arrived nearly 15 minutes late for the live show, leaving Ryan Seacrest to explain to viewers that the “Starships” singer was caught in traffic and leaving the other judges – including an unimpressed Mariah Carey – to critique the first competitor on their own. The 30-year-old eventually showed up, but perhaps she had no time to make it to hair and makeup as she fulfilled her judging duties beneath a black hooded sweatshirt while masking her face with big sunglasses.

Despite instances of unprofessionalism on “Idol” this season – need we remind you of her curse-filled spat with Carey during auditions? – in a new interview, Minaj says she has grand ambitions when it comes to her career.

Beyoncé is no stranger to the camera, and she knows how to keep her fans anticipating every online pic she posts! On Wednesday, the 31-year-old beauty showed off her adventurous side when she posted an Instapic of herself popping a wheelie on a motorcycle! Now that is one daring diva!

But those aren’t the only set of wheels Queen Bey has showed off on social media sites. The “Love on Top” singer posted a snapshot last week that showed her posing in the driver’s seat of a delivery truck and also shared a flurry of photos of herself working at a construction site, driving a forklift, and wearing a blue hard hat!
