Mark Estes is officially dialing a new number.

The Montana Boyz star hard launched his relationship with fellow social media personality Sommer Ray, months after his breakup with Kristin Cavallari.

In a TikTok shared June 1, Mark, 24, playfully lip-synched’s the lyrics to Justin Bieber’s “Baby” as he danced behind Sommer, before pulling her in for a kiss. He let the caption speak for itself as he simply tagged the model.

For her part, Sommer, 28, shared a video on her respective TikTok account in the same setting. The clip began with her in the mirror mouthing the words “I wasn’t sad,” as Mark appeared in the frame and kissed her, while Madonna’s “Holiday” played. And just like her man, she simply captioned the post with his handle.

While Sommer was briefly linked to Machine Gun Kelly in 2020 before he began his relationship with Megan Fox, Mark previously dated Kristin for seven months last year. 

In October, one month after their split, the Very Cavallari star revealed why she called it quits with the social media star.

“I broke up with Mark because I just know long term it’s not right,” Kristin—who shares kids Camden, 12, Jaxton, 11, and Saylor, 9, with ex-husband Jay Cutler—revealed on the Oct. 1 episode of her Let’s Be Honest podcast. “It’s not because of love lost or something bad happened, no one cheated, no one was mean. No one did anything. Those breakups are always the hardest, I think.”

Still, The Hills alum praised her ex, calling him “the best boyfriend I’ve ever had.”

For his part, Mark had nothing but love for his ex as he looked towards the future after their breakup.

“Mark has immense love and respect for Kristin and their time together,” his rep exclusively told E! News Oct. 2. “He’s focused on the future of his business and his project in development with Vice Studios.”
