Olivia Walker and Mark Estes spark dating rumors 

The 'Love Island USA' alum posted a playful video to her TikTok account on Friday, November 22, featuring Kristin Cavallari's ex-boyfriend Mark Estes, nearly two months after their breakup.

"Everyone, I have an announcement," Walker lip-synced as the video began before Estes came into the frame. The two then hugged as they pulled each other in and out of the picture as the iconic song 'Popular' from the musical started playing.

Walker dressed Estes in heels and put his hair up in tiny pigtails as a humorous way to act out the song. She captioned the post, "I think he won prom king in highschool," reported Page Six.

Walker wore a tight white dress and her long blond hair in a straight style, while Estes held his middle fingers up to the camera while sporting a white T-shirt, small fur jacket, and tan pants.

Many admirers rejoiced in her comments section of the post, assuming the playful video was the couple's official relationship debut. However, the couple did not respond to the outlet when asked about the rumors.

"LOVE THIS! You two make sense! 🔥" one social media user wrote.

One individual said, "Now this makes more sense to me. I hope you’re happy Liv! 🥰," while another remarked, "Obsessed with this for you girl 🥰."

Other netizens were a little perplexed as one observer wrote, "Wasn’t he just with Kristin Cavallari or am i trippin???" Some other fans urged the reality TV personality to "run."

Another person commented, "I mean, at least they are closer in age," referring to the 13-year age gap between Estes and Cavallari, while a fifth person said, "Oh Liv....you deserve better."

OK! Magazine reported that Estes' potential new relationship comes after Cavallari's announcement that she is "newly single" at Alex Cooper's live performance in Austin, Texas, in September.

Mark Estes was spotted embracing Olivia "Liv" Walker in a recent video, suggesting that he has moved on after his breakup with Cavallari.

In another post shared by a fan account called @bravobravobravobri on Wednesday, November 20, Estes can be seen standing with his friends in an elevator with his arms wrapped around Walker. 

Although the exact date of the video is unknown, Estes and Walker previously sparked the speculations when they walked the red carpet of 'Gladiator II' premiere in Hollywood on Monday, November 18, according to Life and Style magazine.

The two posted pictures from the premiere to their Instagram accounts, with Walker thanking Paramount Pictures for the invitation and Estes writing, "Heck of a night."

Rumors about Estes and Walker dating each other first began when the Australian posted a TikTok video of the two of them together in Nashville on November 10, where the Kalispell, Montana, native now resides.

The model held what looked like a diamond ring while bending on one knee in front of Walker. "Liv Ellie Walker, will you marry me?" Estes asked with a smile.

She pointed the camera at a friend who exclaimed, "YES!" before exclaiming, "Look at my diamond, baby!" Walker wrote over the video, "Should I say yes?"

Estes' fame reached a new height after meeting Cavallari, 37, when she contacted the Montana Boyz about doing an appearance on her podcast.

Cavallari and Estes announced their relationship to the world in early 2024 but broke up in September after just seven months of courtship.

The TikTok star's representative told Page Six in October that he has "immense love and respect for" the 'Hills' alum, indicating that their split was amicable.

Cavallari, on the other hand, disclosed on her 'Let's Be Honest' podcast that she broke up with Estes because of their distinct long-term goals and his age.

"He’s been the best boyfriend I’ve ever had. I just know long-term he needs to experience life, he’s young. I started to feel the age a little bit with life experience," she said.
