The 27-year-old was sold by the Whites to Newcastle in 2004 after relegation from the Premier League but reveals his family are all still fans of Neil Warnock's side, despite going to watch him play at the Etihad Stadium instead.
And while the Milner clan may have split loyalties on the day, the England international is intent on helping Roberto Mancini's win after losing to Southampton to slip 12 points behind rivals Manchester United in the title race.
"All of my family are Leeds fans and it's going to be tough for them," he told reporters. "My mum and dad had season tickets for years, but they gave them up when I left because they come to watch me.

"But I'll do everything I can to make sure that we win the game. Losing any game is a massive blow and the performance against Southampton was nowhere near the standards we have set ourselves.
"We have to bounce back by winning against Leeds. We have the ability to do it."
Milner revealed the pain of having to leave Leeds prematurely so that the club could balance their books after spending big to earn Champions League qualification, and says he regrets having his Elland Road career cut short.
He added: "When I went in for the first day of pre-season training, they just told me that I was going up to Newcastle for a medical.
"The club needed the money and it was the right thing to do. I am a Leeds lad, a Leeds fan, and the only disappointment I have is that I didn't get to play for them a bit longer."
And although he is Leeds born and bred, he is still unsure of how the Leeds fans will take to him - but suggests it is simply part and parcel of the modern game.
"I don't know what kind of reception I will get," he continued. "I know what they thought when Alan Smith joined [Manchester] United, but you are always going to have some fans who love you and some that hate you. That's football."
