hmm well if she was posting them before that story, imho it's not like she's using that rumor or anything, she seems really funny and crazy and maybe she just jokes about that. maybe she kinda tries to use it, but she's quite successful without Leo and we all know that
now I can't find the link but few days ago I saw an article Rita Ora (if my memory serves me right) said that when she heard that rumor she called Cara and asked if it was true and as she said Cara heard that from press as well... I'll post it if I find the link.
and 100% agree with wijn, Cara is just 20 (same age as me) and Leo is 38 and I totally understand if she said no to him, no matter how good looking Leo is, he's old for her age girl. she's judged cuz as press say she said no to Leonardo DiCaprio, imho she did it right, cuz no need to be his temporarily doll.18 years is a huge age gap and I know how it ends all the time.
