Using him as a rebound?
Does it really matter? at that time it was obvious THEY WERE BOTH HAPPY, and he came at the right time to lift her spirits, and she only ever has NICE THINGS TO SAY ABOUT HIM, so please get off your high horse.
Nick is a human being, he is exactly the same as everyone else, except he along with Delta are famous, so apparently they can’t be rebounds? or people can’t use them? (whether it is right or wrong, I don’t care) but it happens to them too, it’s LIFE. IT HAPPENS. get over it. They both enjoyed each others company, and if you watched it she said “there was genuine love definitely” so THEY DID LOVE EACH OTHER.
Nick is not some precious angel~ or super human who is exempt from real life things, he experiences, love, heartbreak, and I bet other people in his life have ‘used’ him far worse than what you think Delta ever has.
If she was a famewhore do you think she would be over in the US selling her story to the tabloids? once her and Nick were over? YES, but she’s not and she didn’t, she has only ever said nice things about him in interviews (about her) since then, so stfu.
