The Coldplay frontman met up with the One Direction star and Selena Gomez at last weekend's American Music Awards and he couldn't get enough of the 21-year-old hunk's flowing locks.

He said: "We saw One Direction on Sunday. Harry's hair - it's very attractive, even I got a little confused.

"And I met Selena Gomez and she's so great and lovely, I felt so happy, like I was 12."

Chris - who is dating 'X-Men: First Class' actress Annabelle Wallis - loves Harry's long locks so much he couldn't decide who is more attractive - the 1D star or Selena.

He is quoted by the Daily Star as saying: "It's got to the length where I'm like, 'So, who looks better out of Selena and him?' "

This isn't the first time Chris has been full of praise for Harry's tresses.

Last year, the singer said he had a "hot flush" and joked he had to question his sexuality when he clasped eyes on the boy band star's locks.

He said: "[Harry Styles] has come to a couple of our shows. I think I probably said the same thing about chemistry. I can't remember - I was too enamoured with his haircut.

"I was like this, 'I was pretty sure I was a straight guy before.' I was having a hot flush."
