'Hi guys, I just wanted to do a quick insta story obviously the news is now out.
'Tom and I are expecting our first baby together next year. May 2020. I love that it's 2020.
'Anyway I'm so excited. I just want to say thank you to everyone who has been sending me messages.
'I'm actually a little bit overwhelmed to be honest and my fun hasn't stopped. Very exciting times.'
Danielle and Tom went public in September, announcing they were in love via Instagram.
'Life has a funny way of working out just when I decided to give up on love my friend of 22 years swept me off my feet.
'You don’t find love it finds you, it’s got a little a to do with destiny & fate, and what’s written in the stars #mybestfriend #love #happiness'.
Danielle announced the news just months after splitting with boyfriend of two-and-a-half-years, Danielle Spiller.
Danielle is the third member of the TOWIE cast to announce she is pregnant this year. Lydia Bright revealed she was expecting in August and Lucy Mecklenburgh announced her pregnancy just weeks later.
