Although Louis Tomlinson maintained a strong relationship with his mom, Johannah Deakin, up until her death, the same can't be said for his biological father, Troy Austin. According to Metro, Austin and Deakin divorced when Tomlinson was very young, and Tomlinson eventually adopted the last name of his step-dad, Mark Tomlinson. 

Fans learned of Troy's existence in March 2013, when he gave an in-depth interview to The Mirror about his strained relationship with the then-1D star. In the article — which Troy supposedly wasn't paid for — he expressed regret about his falling out with Louis, and spoke about his efforts to reconnect. "Seeing what he's done with his life makes me so happy," he shared. "I know people will think I'm only ­interested in being part of his life again because he's rich and famous. But it's not about that."

Louis seemingly wasn't happy with his bio dad's public move. The same day the interview went live, he tweeted, "I'd like to start off the day by saying a big f**k you to 'the mirror' "

Two years later, Troy allegedly planned to drop a "bombshell" about Louis' life. "He sees it as his final shot at getting Louis' attention," a source claimed (via The Mirror). Apparently feeling protective of Louis, his stepdad, Mark, sent out a tweet seemingly meant for Troy. "Blackmail????????? Stupid man," he wrote. "Got a good mind to pay you a visit!!!!"
