I love Pricey, yes she does need to shut up about her exes though.
But TBH, we only see 45 minutes of footage a day, the other housemates might be interested and inquisitive, so they may be asking her about them. I don't think she just randomly changes the topic of discussion about herself.
She didn't talk about Andre much at all, when she was in the jungle, back in 2009. And that was when it was all over the papers at the time.
