Hills has both Mitbaahy and Khaadem engaged in the Group One and with Jamie Spencer suspended, the ride on the latter is expected to be up for grabs.
The eight-year-old bounced back to form to win the Queen Elizabeth II Jubilee Stakes for the second successive year recently.
Loughnane himself tasted Royal Ascot glory when winning the Coventry Stakes on Rashabar for Brian Meehan and the Sandringham Stakes on George Boughey’s Soprano.
Hills and Loughnane teamed up at Sandown on Saturday to win with the promising Cicero’s Gift.
“Billy the kid – he’s amazing isn’t he and is great for the future of our sport,” said Hills.
“It’s great to have a young jockey like that, he’s very articulate, is a brilliant rider and has great hands and is very astute in a race. I’m really looking forward to watching his career going forward.
“He’s going to ride for me in the July Cup and will maybe take the ride on Khaadem. Jamie is unfortunately banned, so absolutely he will take a ride there.”
