‘The Challenge’ Star Kailah Casillas Shades Joss Mooney When Fan Compared Him to Her Boyfriend, Sam Bird

Real World and The Challenge star Kailah Casillas recently began dating Ex on the Beach star, Sam Bird. The two have already visited each other in their respective countries, and their relationship is seemingly getting more serious.

In an Instagram photo Casillas posted with her boyfriend, a fan claimed he resembled The Challenge competitor, Joss Mooney. The Real World star shaded her co-star with her response.

Kailah Casillas and Mikey P broke up

In February 2017, Real World: Go Big Or Go Home and four-time Challenge competitor began dating DJ Michael “Mikey P” Pericoloso when they made their couple debut at a Floyd Mayweather boxing match.

The Las Vegas-based couple were inseparable ever since, and Casillas frequently talked about him on The Challenge and Lindsay Lohan’s Beach Club. She also modeled for his clothing website, and the couple appeared in a May 2019 episode of MTV’s How Far is Tattoo Far?

However, during filming for the upcoming 35th season of The Challenge, the Real World star allegedly cheated on her boyfriend with UK reality star, Stephen Bear.


In November 2019, he featured Casillas heavily on his Instagram and showed her meeting his friends and family as well as wearing his ring. After returning to the United States, The Challenge star promptly moved out of the Las Vegas place she shared with her now ex-boyfriend and moved back to Florida, where she currently lives with co-star Nany Gonzalez.

Two months later, she began a romantic relationship with Ex on the Beach star Sam Bird.

The UK native flew to Casillas’ place, and the two documented their time together heavily on Instagram. They watched the Conor McGregor vs. Donald “Cowboy” Cerrone MMA fight at a Miami bar, attended a Miami Heat basketball game, went to a Fat Joe concert, and tanned at the beach throughout a four-day period.

She also flew to his hometown of London, England, and hung out with him and his friends. The couple have publicly claimed each other as boyfriend and girlfriend, and Gonzalez seemingly approves of the union.

Some fans think Casillas and Bird have a genuine connection, whereas others doubt the validity of the relationship and believe it’s a ploy to get on another reality show.

On March 2, 2020, Casillas posted a selfie of only of herself and then another with Bird gawking at her. She captioned it, “When he sees you found the perfect lighting” and included a laughing emoji and arrows encouraging users to “swipe right” on the pictures.

Bird commented he was “just checking the view,” and The Challenge co-star, Dee Nguyen, left a heart eye emoji. One user claimed Bird “looks like Joss,” and Casillas snapped back, “not really. Sam’s better looking and actually has a personality.”

It’s unclear if The Challenge star and her co-star, Joss Mooney, have beef, but they both competed on Vendettas and Final Reckoning. Additionally, Casillas was involved in a “bullying” incident where she dumped Kayleigh Morris’s clothing everywhere, causing the UK competitor to quit.

Morris is also Mooney’s ex-girlfriend, so he could have stood up for her, creating tension between himself and Casillas. The Challenge 35 will premiere sometime later this year.
