Rita Ora doesn't have any kids - although this was disputed by one of her ex's - Kim Kardashian's little brother Rob Kardashian.
In what is, I have to admit, one of the most bizarre celebrity stories I've heard on in recent years, it seems Rob Kardashian accused Rita of sleeping around after they broke up, and then suggested she was pregnant with his baby.
This whole "revelation" took place on Twitter back in 2012, and since then Rita hasn't looked at all pregnant, and there have been no further rumours about her having a child.
She did go on to date some other celebrities, including DJ and producer Calvin Harris, although my gossip magazine sources tell me they broke up back in the Summer of 2014.
So to sum up: Rita ora doesn't have any children yet. Maybe that'll change when she meets the right guy.
