The former X Factor finalist and I'm a Celebrity... Get Me Out of Here! winner - who is mother to 3-year-old son Zac from a previous relationship - is expecting a baby with boyfriend Aaron Barham.
Solomon told The Sun: "We are really excited. And I'm really looking forward to everything, knowing I am sharing it with the person I want to spend my life with."
The 22-year-old is due to have her three-month scan next week and added that she is keen to find out the sex of her baby as soon as possible.
Solomon recently signed up to host new Sky Living dating show Love Machine alongside BBC Radio 1's breakfast show host Chris Moyles.
She signed a record deal for her debut album in September and has said that she does not intend to appear on any more reality shows.
