Hard to believe Selena Gomez is comfortable wearing a sweater in the LA heat, but at least she looks adorable doing it.

Justin Bieber's ladylove ran errands in Woodland Hills wearing a big sweater with orange hearts, leather pants and cute boots.

Even covered up, the former Disney darling sure knows how to show off her hot bod!

Justin Bieber loves Drop Dead?

The 18-year-old pop star and his posse took a day off from his Believe tour for some fun at Sky High Sports in Woodland Hills Thursday when he was seen wearing the racy t-shirt belonging to a clothing brand owned by British rocker Oliver Sykes. Interesting choice in fashion, no?

The Biebs wasn't the only celeb in the building that day as bad boy Bobby Brown was at the trampoline park as well. Did these two arrange a secret meet and greet?

January Jones, usually known for her solid color wardrobe, did some shopping in Beverly Hills on Thursday in a Barocco-style paisley silk dress. Way to switch it up girl!

The 34-year-old Mad Men actress has been enjoying every minute with her baby boy Xander but decided to do some retail therapy by her lonesome. A mom's gotta do what a mom's gotta do!

Michael Jackson's oldest son is growing up fast!

Yesterday, Prince Jackson was seen taking a spin in his Cadillac Escalade with a little assistance in Woodland Hills.

The 15-year-old son of the late Michael Jackson has already earned his permit and once February hits, he'll be able to attain his driver's license and be a permanent fixture on the road. Wonder if he'll start driving the family around town?

When Jennifer Lopez attended the Chanel Show in Paris on Tuesday, she was snapped wearing a massive diamond sparkler on her left ring finger, so we have to ask whether beau Casper Smart proposed to her!

We got a peek at the ring when J. Lo stepped out of her car and reached down to grab daughter Emme's hand, and this is definitely one we haven't seen the 43-year-old singer/actress wearing before. J. Lo's manager had no comment on a possible engagement, and her publicist has yet to respond to our inquiries about the ring.

Lopez has been married three times before (she was married to Ojani Noa from 1997 to 1998, then to dancer Cris Judd from 2001 to 2003, and then to singer Marc Anthony from 2004-2011), and she also also engaged to Ben Affleck, but the couple called things off in 2004. Think she's ready to tie the knot for a fourth time?

Just another day in the life for the Kardashian clan!

Kim Kardashian caught a flight out of Miami today, and the reality star doesn't seem to know the meaning of travel style! The brunette bombshell rocked Louboutin pumps and leather pants for her day in the skies, which isn't exactly the most comfortable outfit!

Meanwhile, her momager Kris Jenner was back in LA shopping at Trashy Lingerie. Let's hope the 56-year-old was there to buy gifts, not shopping for a Halloween costume for herself! Just like Kimmy K needs to learn the term "travel style", Mrs. Jenner needs to learn the term "age appropriate!"

Just last night, the E! matriarch took in the Justin Bieber concert with her famous daughters, and she opted to wear leather pants and a see-thru leopard top!

Now we know where the K ladies draw their skimpy style inspirations!

Perhaps Pete Wentz was buying a pick-me-up for his ladylove Meagan Camper?

Ashlee Simpson's rock star ex-beau left Starbucks in Studio City holding two large iced coffee drinks. That's some serious caffeine!

Sporting a simple black T-shirt, MC Hammer-style grey pants and cheetah print sneakers, the Fall Out Boy singer looked like a fashionable man on a mission.

When you start dating a big Hollywood action star, you've gotta keep up in the body department!

Minka Kelly threw on a t-shirt and spandex and headed to the gym for a workout today, and even though the Friday Night Lights actress has always been in good shape, it's clear she's stepped up her fitness game now that's she enjoying new romance with Captain America star Chris Evans!

Considering she dated NY Yankees player Derek Jeter for years, she probably knows a thing or two about proper training techniques!

Interestingly enough, Chris Evans' ex-girlfriend Jessica Biel also enjoyed a brief romance with the baseball star after they split in 2006.

Seems like both lotharios certainly have a type... hot, athletic brunettes!
