WILLIAM GIVES HARRY A SWIFT KICK!

Taylor dragged into brothers' simmering war

PETTY Prince William cozied up to pop princess Taylor Swift knowing all too well his growing friendship with the Cruel Summer singer would set off the snubbed Duke and Duchess of Sussex and now the unwitting superstar is caught in the middle of a royal civil war, palace spies squeal.

William, 42, beamed backstage in London as Taylor and her football player beau, Travis Kelce, snapped after-concert pics with the future king and his two oldest kids, Prince George, 10, and Princess Charlotte, 9.

The Shake It Off songbird even shared one selfie online and wished Wills a happy birthday!

"Taylor is very much on the royals' radar. It's not just Charlotte and George who love her. Everyone's raving about her and how talented and charming she is," a source spills.

"The word is she's going to be top of their list for any upcoming galas or events that involve celebrities."
