A mustache is definitely not a good look for 16-year-old teen sensation Justin Bieber, but you have to admit he's got a great sense of humor!

Actually, even if Biebs wanted to grow a stache, would his prepubescent face be able to sprout any fuzz? All in good time, young Biebs.

Looks like the teen is channeling his idol Chuck Norris. Aside from posting Mr. Norris' picture, he tweets, "No one messes with the stache of Chuck! haha"

Justin already drives a Lamborghini and is dating the sexy Selena Gomez ... so maybe facial hair is the next step. Zac Efron was able to do it, so why not Bieber?

It may have been pouring buckets yesterday, but that didn't stop Rihanna from going on a shoe shopping spree at Barneys New York in Beverly Hills! The R&B hottie took her time looking at Louboutins and other fancy footwear, and even though the rain seems to be washing the pretty off the faces of some of the other starlets out there, Rihanna looked oh so fab.

If the shoe fits...

Paris Hilton and Cy Waits touched down in Maui yesterday afternoon, and they've certainly got the right idea! After 4 days of non-stop rain in Los Angeles, we'd give anything to jet off to Hawaii for the holidays with a hunky man! Paris tweeted:

"Just had a lovely dinner with my whole family. Had the macadamia covered mahi mahi. So delicious! ... So nice to have the entire family together ... Hanging out with my love, @NickyHilton and @DavidKatzenberg. So nice to be with family and loved ones. :)
Hawaii is one of the most beautiful places on earth! So happy to be here! :)"

The lovebirds snuggled up as they left the airport, and it looks like these two are more than ready to hit the beach. Can't wait to see Paris' hot bod in a bikini!

Ali Larter and husband Hayes MacArthur welcomed a healthy baby boy on Monday morning in Los Angeles, her rep has confirmed.

Mother and child are both doing well, and the first time parents have named their son Theodore Hayes MacArthur. "He's our perfect Christmas present," Ali told Us Weekly.

Larter and MacArthur wed in Kennebunkport, Maine in August 2009 after a 7 year courtship, and the Heroes actress revealed that she was eager to start a family back in 2007, telling Cosmopolitan, "I told my boyfriend after three weeks that I wanted to marry him and that we could do it tomorrow...I look forward to that time when I'm home with babies."

Judge Elden Fox was probably not too pleased to hear news of Lindsay Lohan's alleged assault of Betty Ford Center employee Dawn Holland, but could he throw the book at Lohan for possibly having violated her probation?

The troubled starlet is set to leave Betty Ford January 3, but when she appears in court to face Judge Fox at her February 25 hearing things could get complicated. We spoke with Criminal Defense Attorney Barry Gerald Sands who tells X17online:

"The Betty Ford tech reportedly wants to prosecute. If she files criminal charges against Lindsay, that could very well be a violation of her probation in Los Angeles court, which could result in jail time. Judge Elden Fox ordered Lindsay to stay in the Betty Ford center until January and because she has a probation violation already, it is up to Judge Fox to decide to give her another chance. If the staffer files criminal charges this will most definitely complicate her probation."

This isn't good news for Linds! If charges are filed, Judge Fox could order Lohan to serve up to 180 days in jail! Lohan has already spent almost three months at the center working hard on her sobriety and she only has two weeks left! It would be such a shame to see it all thrown away over an argument.

Of course, if Lindsay's dad Michael is right and it was the Betty Ford staffer who b*tch slapped Lindsay first and Lindsay presses charges, Lohan may be able to get out of any trouble with Judge Fox. It's still a somewhat she-says/she-says situation but no doubt some other staffers and perhaps some patients will come forward in each ladies' defense!

Actress Jen Garner, flying solo, stopped by children's boutique Janie and Jack in Santa Monica on Tuesday for a little last minute holiday shopping. Another rainy day in LA! Think SoCal will have a White Christmas by the end of the week?

Not likely! But I think we can all safely assume that supermom Jen will have plenty of presents for her two girls, Violet and Seraphina. And hopefully hubby Ben Affleck will pencil in some family time over the holidays!

After all, she DID just receive a Golden Globe nomination and a Screen Actors Guild nomination for her role in the hit comedy! Why, what did you think I was referring to?

Not only that, Sofia Vergara has upcoming roles in The Smurfs, Happy Feet 2 and New Year's Eve. Wow! Talk about in demand.

Here's the TV hottie outside Letterman in NYC. Such a beauty!

And she's looking as lovely as ever! Nicole Richie married her babydaddy Joel Madden - the couple have two children together, Harlow and Sparrow - earlier this month, and now check out mom Nic running errands in Beverly Hills on Tuesday.

The beautiful bride stopped by Barneys New York (where else?) and Whole Foods.

We miss the elephant already! Of course, PETA wasn't too thrilled with the idea overall...
