Brand-new parents Fergie and Josh Duhamel welcomed their son Axl Jack on Aug. 29, and now they're finally sharing photos of their little bundle of joy from the first days of his life. Spoiler: They're adorable.

Chloe Grace Moretz is just 16, but she is emerging as quite a style star. The actress wears all the hottest designers and is already demonstrating an affinity for heels! There's nowhere to go but up for this pretty and talented little lady!

While we can never keep up with all of the shenanigans on 'Pretty Little Liars,' we do know one thing: That is one good-looking cast! Two of the stars, Keegan Allen and Tyler Blackburn, have gained reputations for their determination to expose A -- and they've looked handsome doing it. Which actor do you think is more swoon-worthy?

If you don't like the idea of Ben Affleck playing Batman, you're really not gonna like this: Justin Bieber might be mulling the role of Robin.

Say what you want about 'Here Comes Honey Boo Boo' and its subject family, but they clearly all adore and appreciate one another. Case in point? The wedding of Mama June and Sugar Bear on the season finale, which brought many a tear to an eye, both redneck and white collar alike.

Two of cable's biggest shows feature some of TV's best-looking men. Enter Aaron Paul of 'Breaking Bad' and Damian Lewis of 'Homeland.' Both actors have earned major props for their roles on the dramas, but they are also known for making fans swoon. Who do you think is more swoon-worthy: Aaron Paul or Damian Lewis?

AshLee Frazier from Season 17 of 'The Bachelor' (aka the season of Sean Lowe) shared a picture of herself in her younger years, and thanks to those dark locks, you can barely even tell it's her. Seriously? Are we sure this is even the same person?

Kailyn Lowry, who you may know from 'Teen Mom 2,' is getting re-married to her husband, Javi Marroquin, in a little over a week -- and the details are all finally coming into place.

Diva Mariah Carey and rapper Nick Cannon's musical prowess may have already rubbed off on their adorable twins, with their son Moroccan Scott (nicknamed Roc) already desiring to grow up and be a rock god. (Or a "roc" god?)

When it comes to Hollywood royalty, no one commands attention on the silver screen quite like Tom Cruise and Johnny Depp. With decades of successful films under their belts, these leading men have proved time and time again they are more than just handsome faces with perfectly chiseled jawlines...

Two of Hollywood's favorite actors are easy on the eyes as well! The past few years have been good to Channing Tatum and Armie Hammer, who have each scored multiple roles in blockbuster movies.

Kate Winslet, who's knocked up with the next generation of little Rocknroll'ers, proved pregnancy agrees with her with a radiant appearance at the Toronto International Film Festival.

Part of the job description for "pop star" seems to include being a teenage heartthrob. One Direction's Harry Styles and Justin Bieber are no exception. These two teens know how to make their female fans go absolutely crazy. Which singer do you think is more swoon-worthy?

When we think of former 'Gossip Girl' star and current Pretty Reckless frontwoman Taylor Momsen, we immediately think of raccoon eyeliner, copious eye makeup, pentagrams and thigh highs, and garter belts as pants. Or, you know, not wearing anything at all. Which is why we were shocked to see her at New York Fashion Week looking like a high-end, high fashion model -- and she even had a mini 'Gossip

Alyssa Milano is 40 and the mom to a young toddler -- son Milo -- but she still emits a youthful, effervescent glow. She's naturally pretty and in possession of a dynamite smile, and her style remains enviable.

Hollywood has its fair share of lovable bad boys. Although

Rihanna can pull off almost any style she wants, but her latest hairstyle is making us question whether even she, RiRi herself, can pull off one particular coif: the mullet. Yes. She went there. And she went to Fashion Week when she went there.

Though casting Dakota Johnson as Anastasia Steele in 'Fifty Shades of Grey' was met with some controversy -- and even a few petitions -- 'Fifty Shades' author E.L. James couldn't be happier about the choice. James was so thrilled, in fact, that she posed for pics with the blond bombshell on the streets of New York City, then showered her with compliments and kind words!
