Made in Chelsea 's Binky Felstead announced she's pregnant with Josh 'JP' Patterson's baby and could not be happier with the news.

The long-standing reality television star took to social media after announcing the news and said: "When you get the best surprise you never knew you always wanted...there's a little "buh" on the way."

The 26-year-old wrote on Twitter about her excitement at "joining the mummy club", despite the couple not being together.
