Forget Caroline Flack! OD's Harry and Amelia Lily?

What a difference a few days (and some charidee work) makes...

Just last week we were all of a flap over One Direction lothario, Harry Styles' reported date with Xtra Factor presenter, Caroline Flack. But this week, he's apparently moved on to Frankie Cocozza's alleged ex, Amelia Lily.

Basically, it's an X Factor love-in.

We hear that Harry gave the X Factor finalist his number during last Thursday's Children in Need concert, organised by Gary Barlow.

But, Lily's remaining tight-lipped over the rumours for fear of angering One Direction's crazy fans who apparently sent Caroline death threats last week.

When asked what went on backstage at the concert, Lily told The Sun: "No way I'm answering that.

"One Direction fans would break my neck!"
