Kailah Casillas is officially off the market!
On Thursday, Aug. 27, The Challenge star announced her engagement to Sam Bird.
"I'm marrying my favorite person in the world," Kailah captioned an Instagram photo showing off her brand new diamond ring. Sam, who gained notoriety on season four of the U.K.'s Love Island, commented on the announcement, "Can't wait for the rest of our life together."
MTV viewers will remember 27-year-old Kailah from her many, many rounds on The Challenge, competing most recently on Total Madness, which aired this year. She also enjoyed a brief stint on Lindsay Lohan's Beach Club, so she's practically MTV royalty.
As for Kailah and Sam's love story, the pair began dating in Jan. 2020 after she slid into his DM's. According to Kailah, who discussed how they met in an April YouTube video, a fan messaged her to let her know that Sam had been liking her photos. Her interest piqued, Kailah reached out to the Brit, who told her, "I'm going to book a trip to come see you."
After doing long distance for some time, Kailah relocated from Las Vegas to London. Since then, the lovebirds have kept their hundreds of thousands of social media followers up to date with frequent photos of Kailah's experience across the pond.
Prior to their engagement, both Kailah and Sam went through showmances.
Kailah's relationship with longtime boyfriend Michael "Mikey P" Pericoloso came to an end after she reportedly cheated on him with her fellow The Challenge competitor, Stephen Bear. Meanwhile, Sam dated Love Island co-star Georgia Steel, but things between them didn't last. Both Sam and Georgia then went on to appear on MTV's Ex On the Beach: Peak of Love, which aired in 2019.
Sam isn't the only star to pop the question this year. Check out our jam-packed roundup of 2020's celebrity engagements right here.
