Hollywood's latest uncomfortable celebrity encounter involves Nicole Kidman and Salma Hayek on the red carpet.

The red carpet can be an intimidating place.

A video of Nicole Kidman and Salma Hayek having a tense moment on the red carpet at the Balenciaga RTW spring fashion show in Paris went viral online. In the video, it appears that Hayek is trying to position Kidman for a photo, but Kidman pushes Hayek's hand away from her.

Despite the awkward moment, videos from a different angle show Kidman and Hayek exchanging pleasantries before being photographed, with Kidman even giving her an affectionate hug.

According to a source, there was no disagreement between the women, and they have a deep affection for one another.

Here are other memorable awkward celebrity encounters on the red carpet.

Ashley Graham and Hugh Grant

After the 2023 interview between Ashley Graham and Hugh Grant on ABC's "Countdown to the Oscars," where Grant was accused of being impolite to Graham, the internet had a lot to say.

Grant replied, "It's fascinating. The whole of humanity is here. It's a vanity fair," when asked about his favorite thing about the Oscars. However, the conversation took a turn for the worse when Graham inquired about Grant's rooting interests, to which he responded, "No one in particular."

Throughout the interview, he gave brief, non-answers, making it the most awkward moment. When asked about his role in "Glass Onion," Grant dismissed it as insignificant, saying, "I'm barely in it for three seconds." When asked if he enjoyed filming, he gave a brief response, saying, "Almost."

Fans swiftly flocked to Twitter, now known as X, to express their dissatisfaction with the actor, with one user commenting, "Hugh Grant, you don't need to be that rude. It's really not necessary."

"Graham told the Sunday Times in August 2023 that he could tell the person didn't want to be there, which was evident. Before they started talking, the person was very pleasant. However, once they began rolling, the person said they didn't want to be there, and Graham responded, 'OK, work with me! I understand. But like, work with me?'"

Kesha and Jerry Seinfeld

In 2017, Kesha felt a bit embarrassed after Jerry Seinfeld declined to hug her during their first meeting at a charity event on the red carpet.

In a viral video posted to X by 94.7 Fresh FM radio host Tommy McFly, Kesha can be seen excitedly hugging Seinfeld, but the actor declined. After Kesha left, Seinfeld turned to McFly, who was interviewing him, and said, "I don't know who that was."

"He stated to Extra a few days later that he is 63 years old and does not know every pop star or everyone. He explained that as one gets older and has accomplished things, they have their own reality. In his reality, he does not hug a total stranger without first meeting and greeting them. He emphasized the need to start somewhere when interacting with others."

In February 2023, the "Tik Tok" singer spoke with Tom Scharpling on his "The Best Show" podcast and shared her perspective on the moment.

"Kesha expressed her excitement because he brings her peace, love, and good things in the universe. However, her mood quickly changed when he failed to hug her in front of cameras, resulting in a depressing and hilarious but also sad moment that felt like the saddest moment of her life."

Sacha Baron Cohen and Ryan Seacrest

During the 2012 Academy Awards, Ryan Seacrest was surprised when Sacha Baron Cohen poured an urn full of "ashes" on him while they were being interviewed on the red carpet.

The actor wore a Moammar Gadhafi costume and carried an urn with Kim Jong Un's face on it at the award show, claiming it contained the dictator's ashes. However, CBS News reported that the urn actually contained flour.

During his interview with Cohen on "On Air with Ryan Seacrest," Seacrest revealed that he was not aware that Cohen would be "sprinkled over the red carpet and over Halle Berry's chest" before spilling a portion of the "ashes" onto Seacrest.

"Seacrest stated, "You never know what will occur or what you'll accidentally spill on yourself. As a host, you must always be prepared for the red carpet. Therefore, I had another jacket.""

Rihanna and Stella McCartney

At the Met Gala in May 2014, Rihanna and Stella McCartney had an awkward encounter while posing together on the red carpet.

The musician, who won a Grammy Award, wore a white two-piece outfit consisting of a long-sleeve crop top and a high-waisted skirt with a small train.

At the Met Gala, Rihanna's dress train tangled around McCartney's heel so tightly that Rihanna had to bend down and remove the shoe herself.
