Selena Gomez Devastatingly Gorgeous at 2011 Billboard Music Awards

Sunday, May 23rd at the MGM Grand in Las Vegas the stars gleamed their brightest, showcasing plenty of red carpet style and a lot of skin. One of those stars just happened to be Selena Gomez, who was there with current beau Justin Bieber.

La Selena kicked off the season with a low-necked number by Dolce & Gabbana in black. The dress sported V-shaped cutouts in the side and a slit-to-there hemline, with not an inch of cellulite in sight.

She paired it with red peeptoe bow heels by Guiseppe Zanotti, jewelry from Nail Lane, and a black clutch bag courtesy Judith Leiber.

Her long hair was worn casually, with a middle parting and makeup was in soft pastels which flattered her face quite well.

The night was not uneventful for the Gomester, 18, who received major PDA from her date Justin Bieber just after he won for Top New Artist.

There's no denying this Disney star has impeccable taste in threads, just as there's no denying she and Bieber rock as a pair.

Penelope Cruz Flirty in Feathers at 'Pirates Of The Caribbean On Stranger Tides' Premiere

Penelope Cruz wowed in a black feathered Marchesa gown at the world premiere of her film 'Pirates of the Caribbean: On Stranger Tides' at Disneyland on Saturday, May 7 in Anaheim, California.

The 37-year-old hot mama flaunted her post baby curves in a custom body hugging, off-the-shoulder gown with a mermaid silhouette, accented with crystal and feather detail.

She accessorized with Chopard jewels- oval drop earrings, bracelet in her left arm and a ring on her right hand ring finger.

Her hair was styled in a high ponytail and forehead framing fringe, the shortest ever that we have seen on her. Angled eyeliner on lids accentuated her thick arched eyebrows. Nude lipgloss rounded her look.

Penelope, who is the newcomer to the fourth outing of the Pirate series, posed on the black carpet with co-star Johnny Depp, who was dressed in black and white.

The premiere, which featured a 2,700-foot-long black carpet lining the Main Street in Disneyland, made history by becoming the first outdoor 3D premiere in the world.

Around 2000 guests attended the screening, paying $1,000 a ticket. The proceeds from the premiere will be donated to the Boys and Girls Clubs of America.

Around 25,000 fans thronged the venue to get a glimpse of the attending celebrities, including Geoffrey Rush, Astrid Berges-Frisbey, Patti Hansen and Keith Richards (cast members); Vanessa Hudgens, Ashley Tisdale, Steven Tyler, Eva Longoria, Natalie Maines, Chelsie Hightower, Cheryl Burke, Eliza Dushku, Emma Roberts, Ian McShane, Kevin McNally, Sam Claflin, Jodie Foster, Martin Short, Teri Hatcher, Kirstie Alley, Joey Lawrence and Cat Cora.

The film opens in theaters on May 20.

This is Penelope's first film after her son Leo's birth in January 2011. She was pregnant with her son during the filming. This is also her first film with Johnny Depp, and her second with director Rob Marshall; the two earlier worked together in Nine (2009).

On April 1, 2011 Cruz received the 2,436th star on the Hollywood Walk of Fame, becoming the first Spanish actress to receive a Star.

Penelope's upcoming films include an untitled Woody Allen Project set in Rome, and Italian director Sergio Castellitto's Venuto al Mondo, a war film in which she plays a single mother of a teenage son. The film is based on an Italian bestseller.

Her long shelved film, 'A Madator's Mistress,' previously titled Manolete, and filmed in 2005, will release on demand via cable, satellite, telco and online on June 7, 2011.

Reese Witherspoon Style at Water for Elephants Spain Premiere

Reese Witherspoon looked smoldering in a black strapless LBD at the Spanish premiere of Water for Elephants at the Cine Comedia on Sunday, May 1 in Barcelona.

Her young co-star Robert Pattinson, looking dapper himself in a grey suit and blue shirt sans tie, wrapped his arm protectively around the 35-year-old newly wed while posing for photogs on red carpet.

Resse's knee length dress had a plunging sweetheart neckline accented with a satin trim ending in a bow.

She accessorized with black peeptoe pumps and let her wedding rock take the limelight as the solo jewel on her.

Her signature blond hair, which she cut a little shorter soon after her March 26 wedding to talent agent Jim Toth, was styled sleek with side swept bangs framing her forehead and accentuating her gorgeously arched eyebrows.

She cheerily signed autographs for her fans before going into the theater for the film's screening.

Reese plays a circus star Marlena Rosenbluth in the film set in the 1930s, and Pattinson plays Jacob Jankowski,a vet with the traveling circus and Reese's love interest. Reese's barely there and revealing gowns in the film and retro structured curly locks are by themselves compelling enough reasons for her fans to go and watch the film.

Jacqueline West is her costume designer in the film.

A former gymnast, the actress breezed through her action sequences in the film without the need of a double.

Water for Elephants opens in theaters in Spain this Friday, May 6!

Reese will be next seen in McG's action comedy 'This Means War' with co-stars Tom Hardy and Chris Pine. The film is scheduled for a February 17, 2012 release.
