The yummy mummy who will NOT give birth on Made in Chelsea hinted that she could get back together with JP, she told the publication: "We're having the most amazing time going on date nights and we're very couple-y.
"It's really nice. We'll see what happens."
Binky and JP haven't had the easiest relationship, they only split up last year but have since announced the shocking news that they're expecting a baby together. The co-stars have been honest with their relationship dynamic, Binky admitted: "I want to be a little family, to be honest. But I'm going to be OK either way.
"Whatever happens, this baby is not going to be affected. And I know Josh will be part of the baby's life whether we are together or not.
"We are a unit now," she told Hello! magazine.
JP also added that they're not going to reunite just because they're expecting a baby: "It has to be for the right reasons. We love each other a great deal, and there's no pressure – but you do have to take the past into consideration, where there have been a few hiccups.
"We're just taking it very easy."
