Jessica Biel puts on a sexy display in a plunging black gown as she is joined by Julianne Hough at pre-Oscars bash

Jessica Biel turned heads on Friday night when she attended the United Talent Agency Oscars pre-party in Los Angeles.

The 42-year-old actress – who marked her recent birthday with sexy snaps – looked phenomenal in a plunging black dress that showed off her breasts.

The former Seventh Heaven star wowed with the long-sleeved look that went all the way down to her midriff.

She added chunky gold bangles to the cuffs of her look and showed off a vampy wine-colored manicure.

Biel was joined at the chic event – which was held at Soho House – by professional dancer Julianne Hough, 35.

Jessica’s light brown hair was parted in the middle and the ends slightly curled.

She looked effortlessly beautiful with a palette of pink makeup on her face, complete with matte lipstick.

For her part, Julianne also opted for a sexy black look with a deeper center.

The asymmetrical strapless dress hugged the star’s slim and fit figure.

Her blonde hair was cut into a sharp, short bob, parted in the middle, with one side tucked behind her ear.

She looked amazing as she glowed in a face of natural-looking makeup that brought out her blue eyes.

The ladies were in good company at the A-list event, where Paris Hilton arrived with husband Carter Reum.

The reality TV star modeled a glitzy hot pink mini dress and showed off her long legs.

Hilton’s long, shiny, platinum blonde locks were placed right in the middle as they flowed down her chest.

She topped off her fun and festive ensemble with a pair of bright pink slingback heels.

Her husband complemented her in an understated black suit and black dress shoes.

The couple cozied up and stayed close as they posed for a snapshot ahead of Sunday’s Oscars.

Also in attendance was actress Tracee Ellis Ross, who posed with former Blackish costar Anthony Anderson.

Tracee looked typically stylish in a boxy black blazer and red tights, which she teamed with her red lipstick.

Next to Anderson, she posed with Barbie director Greta Gerwig.

Gerwig smiled as she arrived wearing a black leather jacket over a green, white and black striped shirt.
