Well, this might be why!
The tattooed reality star, who made his debut on last night's episode of the MTV show, is the brother of former X Factor contestant and Stereo Kicks singer Casey Johnson.
Good looks clearly run in the family!
Chet has been a huge supporter of Casey's music career, sharing the above photo last year when Casey arrived home to surprise the family.
He said: "Words can't describe how proud I am of my little brother. He had only 1 day off today as he's away on tour and he surprised us. Look how happy I am to see him. we shared a room all our life I miss him man lol n this natural picture shows how happy I am lol so proud of you @caseycodyj love you bro!!!! Smashing it with @stereokicks."
Chet arrived on Ex On The Beach last night as Helen Briggs' ex. But rather than the usual drama between two exes, there was nothing but love. They were both thrilled to see each other and we're totally predicting romance is going to blossom again!
EOTB continues Tuesday at 10pm on MTV.
