2013 MTV Movie Awards: Worst Red Carpet Looks; Taylor Lautner, Rebel Wilson, Macklemore and More [PHOTOS]

The 2013 MTV Movie Awards had no shortage of entertainment Sunday night with everything from host Rebel Wilson flying in a female “Iron Man” suit to Seth Rogen flashing his pubic hair. But perhaps the most amusing aspect of all was the head-scratching, unflattering and sometimes offensive celebrity outfits.

Here are five of the worst looks from the 2013 MTV Movie Awards:

Hana Mae Lee

“Pitch Perfect” star Hana Mae Lee told MTV that she helped design the Alain Lafaille for He-Ha unique cigarette butt hat.

“I’m not promoting smoking or not smoking at all. It’s just a fun sculpture on the head,” Lee said. "I just think cigarettes, when they're smoked, just look so ugly and interesting on the ground or in an ashtray. So why not wear a little cigarette on your head and beautify what sometimes is considered really ugly?"

The actress finished her look with a Marco Marco dress and laced-up Ferragamo heels.

Taylor Lautner

“Twilight” star Taylor Lautner has been known to shown up to the MTV Movie Awards in well-tailored suites. The 21-year-old changed up his appearance this year rocking what appeared to be a worn-out blue button-down top, jeans and a backward New York Yankees cap. But his best accessory was his fake beer belly. He no doubt wore the outfit to poke fun at his “best shirtless performance” win, or perhaps it was a jab to MTV for snubbing “Breaking Dawn Part 2” in all but one category.

Rebel Wilson

Australian native and “Bridesmaids” star Rebel Wilson wasn’t afraid to show off some skin as she served her role as first-time host of the MTV Movie Awards Sunday. The actress spent the majority of the show in a tight-fitting pleather jumpsuit only to change into a sequin purple number later on in the night. The dress flattered the comedic actress until she whipped out her prosthetic nipples, ruining it all.

Macklemore

In true Lady Gaga fashion, musician Macklemore showed up to the awards sporting a fashion better fitted for the circus. The “Thrift Shop” rapper sported a unique electric blue suit paired with a matching blue cape and gold fringe. Macklemore told Twitter fans Sunday that the eccentric design was created by American fashion designer Logan Neitzel.

Will Ferrell

Comedian Will Ferrell was bombared on stage Sunday night by “Parks and Recreation” actress Aubrey Plaza and even renewed his vows to his “wife” on stage. But nothing could upstage the 45-year-old's outfit. Ferrell was seen rocking a suit with a money print pattern -- something jarring to see on anyone, especially the funny man’s six-foot frame.

Kesha

While Kesha’s eclectic wardrobe isn't exactly shocking, it was her random pairing of a black sun hat and dark lipstick with apparent beach attire that has us all confused. Kesha’s outfit reminded us of an omage to gothic teen Lydia in “Beetlejuice” if she was a peroxide blonde.
