Star sightings: Christina Aguilera, Rachelle Lefevre, Amber Valletta
We've got sightings of "Twilight" star Rachelle Lefevre, model and mom Amber Valletta, movie-making vamp Christina Aguilera, crooner Usher and more.
Soul singer Aguilera, who's getting her first at-bat in a feature film, was spotted on L.A.'s Sunset Boulevard today filming "Burlesque." The slender songstress stars alongside Cher and Kristen Bell as a small-town girl who pursues her musical dreams in Hollywood.
Former "Twilight' vamp Lefevre is helping make dreams come true as well, for the furry set ...
The redhead attended an advocacy benefit on behalf of dogs and cats, over the weekend at the home of actress Emmanuelle Vaugier (who graced "Two and a Half Men" as Mia, a love interest to Charlie Sheen's character). The gals enjoyed Grey Goose cocktails, and Lefevre got compliments on her "Puppy Mills Bite" T-shirt.
Model Valletta also scored compliments on her ensemble over the weekend: She wore an orange RM by Roland Mouret cocktail dress with constructed shoulders at the Grove for the premiere of her new flick "The Spy Next Door."
Always fashionable, Usher graced clubgoers at Haze nightclub with several tracks from his forthcoming album. The club is inside the Aria Resort & Casino in Las Vegas' new CityCenter.
The "Confessions" singer wasn't the only one in Sin City -- friends of the Ministry spotted TV couple Aaron Paul ("Big Love") and Jessica Lowndes ("90210") dining alone at swanky Lavo, sharing one of the restaurant's famed Kobe beef meatballs.
Sans boyfriend but plenty chic, singer Kristine Elezaj dined at Soho's Cipriani. Her second single, "Souvenirs," has a sexy new video. Check it out here!
