Hollywood A-listers and music stars alike have stepped out in style to 2011 Teen Choice Awards. Among those looking lovely when hitting the blue carpet rolled out outside the Gibson Amphitheatre in Universal City, California on Sunday, August 7 were none other than Taylor Swift and Selena Gomez.

21-year-old Swift, who will be receiving the Ultimate Choice Award, presented a Marilyn Monroe-inspired look. She wore a white halterneck dress from Rafael Cennamo, which she paired with a Ranjana Khan belt, Neil Lane jewelry and a pair of Fendi shoes. Completing her look for the evening, she pulled her hair back in a ponytail.

19-year-old Gomez, in the meantime, opted to go by a glamor look by donning a silky, gold Erin Fetherston dress with a creme ribbon. While her boyfriend Justin Bieber also came to the awards show, she walked the blue carpet solo and had a ball posing for the camera with friend Demi Lovato, who dazzled in a yellow mini dress.

Bieber himself brought his style to the blue carpet. Giving a touch of formality to his casual style, the "Baby" hitmaker lets his bowtie hang loose over a button-down shirt and leather vest. He is up for five awards, including Choice Male Artist, Choice TV Villain, Choice Red Carpet Male Fashion Icon and Choice Male Hottie.

Going for a bit more casual look was Nina Dobrev. The Elena Gilbert of "The Vampire Diaries" sent out a summery feel with her blue gingham dress by Dolce and Gabbana. She paired up the dress with a pair of navy Ferragamo heels. Her co-star and rumored boyfriend Ian Somerhalder, meanwhile, kept it completely simple in a gray T-shirt and jeans.

Other stars spotted making their grand entrance through the blue carpet included "Vampire Diaries" hunk Paul Wesley, "Twilight Saga" stars Taylor Lautner and Ashley Greene, "Gossip Girl" beauty Blake Lively, "Glee" actors Cory Monteith and Darren Criss, as well as Kim Kardashian and her sisters.
