From Lucia: There is a story behind these necklaces. Harry recently bought Taylor one to match his. He has had his for a long time, but it has taken on a deeper meaning since these two met and had a short-lived romance.
Apparently, it signifies the distance between the two and how their love is like paper airplanes and just glides through the air. Cheesy, I KNOW, but we’ve all seen that poem he wrote his ex-gf when he was younger..
UPDATE: Taylor pictures added from Paris. Photos: FameFlynet.
