Beyoncé And Bianca, Dr. Dre And Warren G: Celebrity Step-Siblings
Catelynn Lowell and Tyler Baltierra
The stars of the original Teen Mom series, who are currently planning their wedding, were actually step-siblings at one time. No worries, they no longer are. You see, Lowell’s mother, April, married Baltierra’s dad, Butch, after finding out that their children were dating (shady). But Butch allegedly abused April and couldn’t stay out of trouble. He is now in prison, and April finalized their divorce in 2014, only to turn around and get married again near the end of the year.
