Lady Gaga, Rooney Mara and More In This Week's Best & Worst Beauty (PHOTOS)

Lady Gaga is officially back, guys. The singer has a new album in the works, so of course she is also stepping out in some of the weirdest face paint we have seen her wear so far.

On the brighter (er, less bright) side, side-swept hair made waves on the red carpet this week. Stars like Keri Russell and Shay Mitchell pulled it off beautifully, while others such as Vanessa Hudgens and Bella Thorne stumbled with their hairstyle choices.

Check out our picks for the best and worst beauty looks this week.

BEST: Keri Russell

Hot pink lipstick for the win! Russell rocks this tricky shade by letting her shiny side-swept locks and neutral eye makeup act as a subtle backdrop for the bold color.

WORST: Lady Gaga

We're having serious Heath Ledger "Joker" flashbacks with this strange look. Aside from her insane rainbow makeup, Gaga's hair extensions need maintenance immediately.

BEST: Shay Mitchell

Mitchell exudes confidence with this sexy look. Her side-swept waves have the right amount of volume, and we love her nude lips.

WORST: Vanessa Hudgens

Hudgens' dress is already busy, so she really didn't need to wear such an intricate braided hairstyle. It also doesn't help that her two-toned hair resembles a bird's nest.

BEST: Selena Gomez

It's great that Gomez kept her makeup light and fresh because her nails and earrings are what make this look. She taps into fall beauty with a dark manicure, and her turquoise earrings complement her deep hair and hunter green dress.

WORST: Hailee Steinfeld

Steinfeld's smokey eyeshadow is too dramatic for the splashy dress she is wearing. If the color didn't extend to her brow bone, it might have looked more flattering.

BEST: Rooney Mara

We personally think that Mara doesn't need more than mascara and groomed brows to accentuate her deep green eyes. But we also can't get over her edgy, slicked-back hairdo with the contrasting texture on the ends.

WORST: Bella Thorne

Thorne's ginormous side braid is overpowering her natural beauty. A sleeker plait would have paired perfectly with her blunt bangs, winged eyeliner and pink lips.
