Miley Cyrus sports high-waisted, stonewashed denim. (Anthony/PacificCoastNews.com)Miley Cyrus broke out the "mom jeans" again on Thursday in L.A. For the second time in three weeks, the 19-year-old sported a high-waisted, stonewashed pair of cropped jeans -- this time under an oversized red blazer and a sexy black bustier. (You'll recall that the last time she was spotted in the '80s-inspired pants, the actress/singer opted for a red cropped top while lunching with boyfriend Liam Hemsworth.) Miley even had a slight wardrobe malfunction moment when she stepped out of her car with her denim undone. Whoops!

SWAP / Splash NewsStill glowing from her double win at the Grammy Awards for best country song and best country performance of "Mean," Taylor Swift stepped out to dine at L.A. eatery Toast on Wednesday. The fashion plate was decked out in a polka dot dress by Dolce & Gabbana, although the 22-year-old recently confessed to "Access Hollywood" that she's not out to impress any certain guy with her stylish ensembles.

Norman Jean Roy/DetailsLiam Hemsworth, who you probably know best as the guy beside Miley Cyrus in paparazzi pictures, is soon to become a star in his own right once "The Hunger Games" film, based on the massively popular series of books, hits theaters March 23. The Aussie actor, who's been Cyrus' on-again, off-again boyfriend since they met while filming 2010's "The Last Song," plays Gale in the high-profile flick, the best friend of Katniss (Jennifer Lawrence), the main character who volunteers to take her little sister's place in an annual fight-to-the-death between children.

Justin Bieber donned extremely baggy pants for the date night. (Felipe Ramales/PacificCoastNews.com)When you're the reigning prince and princess of teen pop music, do you really need to be bothered with a little thing like the Grammy Awards? For Justin Bieber and Selena Gomez, the answer is no. The cute couple skipped music's biggest night and decided to grab dinner at Chanpen Thai Cuisine in New York City instead.

The pair, who was noticeably absent from the Grammys ceremony on Sunday, still made their presence known by tweeting supportive messages to their friends, with Justin saying, "@officialAdele, well done," and "congrats to all the winner's tonight. Glad to see friends of mine doing there thing. Next year we are coming with #BELIEVE."

Miquel Benitez/Getty ImagesTime really flies when you're hooked on a romantic vampire saga like "Twilight," doesn't it? It seems like it was only yesterday when we were introduced to Taylor Lautner. He was 16 when the first film in the series was released in 2008. (Sure, his resume includes movies such as 2005's "The Adventure of Shark Boy and Lava Girl," but "Twilight" was his breakout role.) And almost four years after Taylor's debut as Jacob Black, we've seen the actor transition from a werewolf pup into a bulked-up man who's turning 20 on February 11.

Twi-Hards can mark Taylor's big 2-0 with the release of the "Breaking Dawn - Part I" DVD and Blu-Ray, which -- conveniently enough -- hits stores on the heartthrob's special day. Hardcore fans have probably already made plans to watch a scene from the final film, "Breaking Dawn - Part II," at Target stores previewing it on the night of February 10, and no doubt they'll snap up the film as soon as it's available at midnight.

It's hard enough being a teenager, let alone one whose life is played out on TV for millions of people every week -- oh, and whose older sisters just happen to be the mega-famous Kim, Kourtney, and Khloe Kardashian. But Kendall and Kylie Jenner have managed to maintain level heads despite the paparazzi, modeling gigs, and millions of Twitter followers. Their secret? "They are so down-to-earth," Kim tells Teen Vogue of the magazine's March cover girls. "It's just who they are, and they will never change."

Has Valentine's Day come early on the set of "Gossip Girl"? Former frenemies Dan Humphrey (Penn Badgley) and Blair Waldorf (Leighton Meester) were snapped in a lip lock while filming the CW show in NYC on Monday. The pair has been growing closer over the past two seasons, with Dan even attempting to help Blair make a run for it to the Dominican Republic for a quickie divorce after she exchanged vows with Monaco's Prince Louis (Hugo Becker) last week.
