Selena Gomez Kills It In Plunging Silver Gucci At LACMA Art & Film Gala

Selena Gomez certainly gave her ex Justin Bieber something to think about on Saturday.

The actress-singer stepped out after a low-key Halloween in a gorgeous, plunging Gucci silver gown at a gala honoring director Quentin Tarantino, and conceptual artist Barbara Kruger.

Selena showed off ample cleavage while posing on the black carpet at the Los Angeles County Museum of Art (LACMA) Art & Film Gala.

During one of the interviews she gave with supermodel pal Cara Delevingne — who wore a one-shoulder black dress — the pals revealed they got ready for the star-studded event together.

The duo looked as if they had a laugh at the party, and were also pictured having fun with actress Kate Beckinsale.

The Gala was hosted by co-chair Leonardo DiCaprio, with LACMA Trustee Eva Chow and Gucci Creative Director Frida Giannini also presenting.

Joining Selena and Cara at the museum were Tarantino’s Django Unchained stars Jamie Foxx and Christoph Waltz.

Other big names included, Cindy Crawford, Salma Hayek and her husband Francois-Henri Pinault, Will Ferrell, Kate Hudson, Michelle Rodriguez, Ryan Seacrest and Demi Moore.

Also attending were, Kate Hudson, Boy George, Florence Welch, James Franco, Garrett Hedlund, Kirsten Dunst, Jennifer Lopez, Kanye West and Kim Kardashian and more.

After the soiree, Selena captioned a shot of herself and Cara on Instagram, writing, “Such a beautiful, inspiring night at @lacma.”

The “Come & Get It” singer completed her sophisticated look by wearing her straightened, brunette hair parted to the side, with a tiny flick at the ends. Her makeup was a palette of soft browns, bronzes and beige/nude lips.

Both Cara and Selena previously unveiled their friendship while celebrating Gomez’s 22nd birthday in St. Tropez, and it’s probable the two provided each other with support following high-profile splits from their partners.

Rodriguez and Cara had a highly public fling months ago were snapped making out in the front row at a Knicks game.

Meanwhile, Selena’s reported breakup with Justin shows no public signs of thawing yet, despite recent reports claiming the Disney alum believed she had “overreacted” after her alleged spat with her former beau.

On October 1, the starlet flew home alone from their Paris Fashion Week trip, the day after the “Boyfriend” singer took model Kendall Jenner to lunch.

The Rudderless actress was later spotted at LAX airport with her ex-boyfriend’s nemesis Orlando Bloom, before they jetted to the We Day youth empowerment event in Vancouver, Canada. Dating rumors were later denied by Bloom.

It’s been reported Justin’s recent stay in New Jersey with Pastor Carl Lentz of the Hillsong Church NYC, is part of a religious retreat and a response to his split with Selena.

Some have speculated that he is “depressed” after Gomez reportedly refused his attempts to rekindle their relationship.

Whether the Canadian is depressed hasn’t been confirmed and is unlikely to be.

Unlike his ex-girlfriend, the heartthrob did step out for Halloween after flying back to his father’s home in Ontario, Canada.

For her part, Selena stayed in bed with girlfriends for Halloween and posted an Instagram of their night in.

But, judging from her turn at the LACMA Gala, the pop princess won’t be single for long.
