Selena Gomez, Kim Kardashian and UK model Cara Delevingne unleashed a virtual barrage of boobs today (Sept. 30) at Paris Fashion Week, wearing designs with eye-opening plunging necklines at a closing night party.

The celebs made their revealing appearances at the CR Fashion Book Issue No 5: Launch Party, which marks the end of the week-long event.

Selena was in Paris along with boyfriend Justin Bieber. But the pop singer made a bee-line for model and reality TV celebrity Kendall Jenner on Tuesday night.

They were spotted having dinner in Paris; Selena was no where in sight. He wined and dined Kendall at chic restaurant Ferdi, a romantic hot spot popular with couples, according to London’s Daily Mail.

Oddly, Selena and Bieber flew together and arrived in Paris on Monday.

Later the same night, Selena posted a sexy selfie on her Instagram account. It look as though she was trying way too hard to hold Bieber’s attention.

Selena kept her distance. She had a falling out with Kendall and sister Kylie Jenner earlier this year.

Gomez un-followed the sisters on her Instagram account in April after spending a weekend with them at the Coachella Music Festival. She allegedly called them “toxic.”

If Selena was feeling alone in Paris, she could always hook up with her gal pal, Cara. The two spent a risque holiday together in St. Tropez in July to celebrate Selena’s birthday.

Cara, 22, was at the event wearing an equally seductive outfit that barely contained her pert breasts. The pantsuit only had wide straps for a top that led to high-waist black panties, visible through sheer pants.

Delevingne was on a working vacation in Paris and walked in several shows. She also shared a catwalk with Kendall in the Chanel show today and led a mock protest as part of the spectacle.

Cara has been romantically linked with “Fast and Furious” star Michelle Rodriguez .

Tisci escorted Kim to the event. Kanye was nowhere to be seen.

UK Model Rosie Huntington Whiteley must have also gotten the memo on wearing a super sexy dress.

Rosie veered away from the all=black look with a pantsuit that combined black, white and yellow-gold stripes.

Boyfriend Jason Statham stayed home, so Rosie spent the evening with Balmain designer Olivier Rousteing.

She’s a fixture for brands such as lingerie retailer Victoria’s Secret and Burberry, the English fashion house.
