Justin Bieber makes an appearance on The Ellen DeGeneres Show today, and the pop star shows off his new tattoo, chats about meeting the Prime Minster of Canada and he even reveals his feelings on being snubbed by the Grammys this year.

When Ellen asked his thoughts on not receiving a single Grammy nom this year, Justin said, "[It was] a big bummer, I would say that it’s definitely, I was looking forward to but I know it will happen one day ... I’m so young. I’m only 18. I’m just blessed to be able to do what I love everyday. And the AMAs was a lot of fun for me..."

On the controversy surrounding his outfit when he met the Canadian Prime Minster, Bieber defends his decision to wear overalls, saying, "I was at my concert. That was at…. I was doing like a meet and greet. Meeting all my fans and stuff and he came to venue where I was performing ... I know it wasn’t fair but that was really my event….I really promise if I would of went to his environment. I would have been all done up."

Biebs also had a big surprise ... check out the video below to see what it is!

Must have been chilly in Spain last night!

Tom Cruise and Rosamund Pike struck a pose at the Madrid premiere of their new action film, Jack Reacher, and the 50-year-old actor looked more like a soccer dad than a movie star. While Tom's fashion choice was a bit debatable, we find it interesting that his 5'9" co-star was wearing a pair of 5" Louboutin pumps, and she wasn't that much taller than him. Is Tom wearing lifts? Or is Rosamund slouching? We're so confused!

While Tom is about 5'7", the character he plays in the flick is supposed to be about a foot taller, and many fans questioned the casting choice. When Tom introduced the first footage of the flick at CinemaCon last spring, he joked, “For those of you who know the books, I'm obviously not 6'5", like Jack Reacher. But Lee felt that I was the right guy to drive fast cars and kick the sh*t out of people onscreen.”

As long as he gets the job done, we don't care!

Woah, is that you?

Kristen Stewart tried to let her sexy side out on Thursday night when she arrived in a see-through Erdem dress at the premiere of On The Road at the SVA Theater in New York City. We're a little shocked!

The 22-year-old actress didn't necessarily shine in her sheer outfit as she switched it up with a black leather jacket and jeans while heading to the after party at Abe & Arthur’s in the city's Meatpacking District. The casual look definitely fits her better!

After two seasons as judge on The X Factor, L.A. Reid is calling it quits as the music mogul will not return for a third season.

"I have decided that I will not return to The X Factor next year," he told Access Hollywood. "I have to go back and I have a company to run that I've kind of neglected and it saddens me a little bit, but only a little bit."

Reid insists that his decision is based around work as he wants to get back to business as the chairman and CEO of Epic Records.

“I have a huge responsibility to a roster of artists and it’s kind of time for me to stop doing the ‘me’ show,” he said. “It was fun! I had a great time.”

Someone's pretty giddy!

On Thursday, Hugh Jackman was the latest celebrity to receive a star on the Hollywood Walk of Fame.

Anne Hathaway and Amanda Seyfried were in attendance to help celebrate Hugh's big day. Add that to his SAG and Golden Globe noms for his work in Les Miserables and it equals one big week for the Aussie actor!

What a happy family!

Hilary Duff and Mike Comrie decided to give their son Luca a little culture as the three took a trip to the Los Angeles County Museum of Art on Thursday.

The 25-year-old actress and her family have been pretty cozy lately and she's even looking better and better after shedding the baby weight. No wonder she's all smiles!

This is definitely her color!

Reese Witherspoon left her infant son Tennessee at home for a lunch date at The Tavern in Brentwood today, and the bubbly blonde got into the Christmas spirit with a bright red dress that showcased her amazing post-baby weight loss!

The Walk The Line star is apparently slimming down with the help of fellow new mom Jen Garner! "Both of them have a serious sweet tooth. Whenever Reese wants to reach for a chocolate bar she calls Jen instead, and vice versa," a source tells Star. Both lovely ladies count The Tavern as their favorite local eatery, but from the sounds of it, they are forgoing the delicious paninis in favor of salads!

The Oscar winner might not be indulging in Christmas feasts, but she is looking forward to the holidays with her new baby boy! "We're going to do fun things. We already bought him a cute little Santa's helper outfit and we're excited about that. That's going to be lots of fun," she recently told E! Online about her celebration plans.

You look ravishing Reese, so go ahead and treat yourself to a cheat day!

Ben Affleck was spotted with daughter Violet after school on Wednesday, and we're not sure who is dressing the hunky actor these days, but he's definitely been picking out some dapper outfits!

And in case you really like Ben all dolled up in a suit, you'll definitely see him at the Golden Globe Awards next month, as his latest flick Argo earned him a Best Director nod, along with 4 other nominations, including Best Picture. Congrats!
